--- begin forwarded text X-Sender: aboss(a)vm.temple.edu Mime-Version: 1.0 Date: Tue, 2 Dec 1997 08:19:51 -0500 Reply-To: Digital Signature discussion <DIGSIG(a)VM.TEMPLE.EDU> Sender: Digital Signature discussion <DIGSIG(a)VM.TEMPLE.EDU> From: Amelia Boss <ABOSS(a)VM.TEMPLE.EDU> Subject: State Department Advisory Committee Meeting To: DIGSIG(a)VM.TEMPLE.EDU I previously posted an announcement concerning a meeting of the State Department's Advisory Committeee on Private International Law on the digital signatures. There have been two changes. First, the location has changed. It will now be held at the Department of commerce, Conference Room 5855 beginning at 9:30 on Monday, December 15 (until 4:40pm). Second, it will be a *one* day only meeting. If you are planning to attend, please notify Rosie Gonzales at the State Department: (202) 776-8420; fax 202-776-8482; email at pildb(a)his.com. Or, call Brian Hengesbaugh at the Department of Commerce: 202-482-4620, fax 202-482-4076. In order to register for the meeting, they will need your name and government agency identification (if any), or affiliation and address, as well as phone, fax, and email address if available. Entry to the Commerce Department should be through the main entrance on 14th Street between Constitution and Pennsylvania Avenues. Hotel Accommodations: There are two hotels that have agreed to offer, on a space-available basis, rooms at the government rate ($108/single; 128/double). However, you must advise the hotel when making arrangements that you are a State Department invitee and that the government rate should be applied. They, in turn, will contact the L/PIL to verify (authenticate?) that you are on the list of attendees, so please make sure that you have followed the procedures in the previous paragraph. The two hotels are the Windham Bristol Hotel at 2430 Pennsylvania Avenue NW (walking distance to State and two blocks from Foggy Bottom metro) [202-955-6400; fax 202-955-5765] and the State Plaza Hotel at 2117 E Street NW (across from the State Department) [phone 202-861-8200; fax 202-659-8601].

As long as blocking requests are authenticated with some sort of "cookie" token scheme, that would be acceptable. That goes for INDIVIDUAL blocking requests. Somewhat more discretion ought to be used for requests to block an entire domain. That should probably only be done upon request from the "postmaster" at that domain, and when an entire domain is blocked, that fact should probably be announced in advance, publicly, in alt.privacy.anon-server to inform users in that domain who might not have been made aware of the action and who might need to recreate 'nym reply blocks, etc., before their incoming mail gets embargoed. For example, if I had a 'nym with a reply block that directed replies to my e-mail account at work (I don't, BTW), and my employer decided that it no longer wanted its employees to be able to receive anonymous e-mail, then it would only be polite for the employer to notify the employees well in advance of that policy change. But in case the employer failed to do so, a public notice should also be made. In fact, I'd say that domain-wide blocking requests should only be accepted from "postmaster" or one of the contact addresses listed with InterNIC for that domain. One large ISP, for example, allowed a user (who was not an employee nor a representative of the ISP) to sign up for the user ID "abuse". > >I would also like to see From: pasted in. In fact I can see no > >purpose to restrict what can be pasted in, other than to reduce > >complaints to the remailer operator possibly. > > Too easy to be abused by forgers, as are Reply-To: and Sender:. I'm not sure what the actual use of a "Sender:" header is, but pasting in a "Reply-To:" header is not technically forgery, since it does not imply where a message came From:. It is only a suggestion where replies should be directed. When the From: and Reply-To: lines both exist, but differ, most software gives the user an option of which address to reply to. Thus, in the final analysis the person replying makes and is responsible for the decision as to where to send his reply. > >My software shows be all headers.

It has been suggested that the practice of pasting in a From: header should not be allowed because it is subject to abuse and that this can better be accomplished through a 'nym server. But if the person doesn't want e-mail replies, why should a 'nym server be burdened with maintaining a reply mechanism that the 'nym owner doesn't want to use? Even if the reply block is redirected to /dev/null(a)somedomain.com, handling replies, incoming mail bombs, etc. is unnecessary work. The fact that the remailer net has implemented source-level blocking upon request means it already has more safeguards in place against "forgery" than 90% of the ISPs have. It's quite ironic to see people like Gary Burnore complain that allowing a remailer user to set an arbitrary From: is "abusive" when the ISP he (and you) post from, Netcom, allows that very thing. There are actually two valid reasons I can think of to paste in a From: header: One is to post "from" a pseudonym without having to go through the 'nymserver. For example, to make posts and send correspondence when the 'nym server is down or to be able to post from a non-secure site without having to compromise security by making one's PGP secret keyring accessible at that site. The second reason would be to post using a non-replyable pseudonym. Many newsreaders gather only the headers of Usenet messages and list them by their Subject: and From: lines. Without the ability to set a From: line, one's posts to a thread are indistinguishable from all the other ones from "nobody(a)replay.com". If I want to call myself "Santa Claus", it's far easier to paste in a "From: Santa Claus <sclaus(a)northpole.gov>" than to go to the trouble of creating a replyable 'nym at a 'nym server just to put something recognizeable in the From: header. The problem with eliminating any feature that gets abused is that it's an open invitation for someone to deliberately abuse it just to get it eliminated. Whenever possible, a solution should be sought which eliminates abuse while still allowing legitimate use. - - -- Finger <comsec(a)nym.alias.net> for PGP public key. - -----BEGIN PGP SIGNATURE----- Version: 2.6.3i Charset: noconv iQEVAwUBNIQzwwbp0h8ZvosNAQFLpgf+LS9VIGvUV3JKRHp+/ZtoRUkhNgH0h2Jg tr/5gazeo+k0EHnaA/jvdnZ2HKSSkKguXaAnzejBnTtfvfQa38GcWBZsve/4fC9e YAv80++wGj/0RhgwNEp8ovm57u5KQmybOqxmfeQ8H/cc8jyfhZEBGb2sxIbqvze5 NvzMGUHpKfUfduxo+kGeoOPOO+CkpM1sd5RmFSPojd6DgG3gNELjLD1jWLpZT7BC YlBOJFh39ibssjQQO1lcLokdgqlDLQZWx1Lar9fyuWHlO5z+2wKkI+MICMkF32YE dd3sPuhZxEGZGHyV+gybqm961G/7VctAXWrKlXuELb1HYUpsSkU+GA== =Q+h9 - -----END PGP SIGNATURE----- ~~~ This PGP signature only certifies the sender and date of the message.

USA Today editorial opposing criminal copyright bill
by Declan McCullagh 17 Dec '03

17 Dec '03

An opposing view from Rep. Goodlatte also appears at the URL below. My article on this unprecedented criminal copyright bill is: http://cgi.pathfinder.com/netly/opinion/0,1042,1588,00.html -Declan ====== http://www.usatoday.com/news/comment/nceditf.htm USA Today Editorial 12/01/97- Updated 11:14 PM ET Law limits use of Net In 1994, Massachusetts Institute of Technology student David LaMacchia invited on-line users to download $1 million worth of copyrighted computer software that he'd put on the Internet. In spite of his antics, charges against LaMacchia were dismissed. Thanks to a legal loophole, hackers who break copyrights just for fun can't be criminally prosecuted. LaMacchia's case is just the most notorious example of how the growth of the Internet has strained the nation's copyright laws. Duplicating materials in cyberspace is as easy as clicking a mouse. The market for pirated goods is as infinite as the World Wide Web. And under copyright laws from the 1800s, infringement occurs only if a person makes money from the illegal act. Determined to deter the hackers, Congress passed a bill last month making it a felony to duplicate copyrighted materials on line, including computer software, recordings, books and articles. But the bill awaiting President Clinton's signature puts more than hackers at risk. It threatens the actions of scientists, academics and Web users, exposing them to criminal penalties of up to six years in jail. Researchers frequently use the Internet to distribute articles that they write but that other publications copyright. And the Internet now plays an important role in peer review. Scientists post their published research on a Web site in hope of encouraging the exchange of scientific information. Until now, copyright infringement wasn't a worry for these folks. Courts recognized the "fair use" of copyrighted works for noncommercial purposes, including teaching, research and criticism. To bar the use of all copyrighted material would be like telling film critics they couldn't quote dialogue in their movie reviews. Yet under its new law, Congress makes it a crime to duplicate copyrighted materials on line but neglects to include specific "fair use" legal protections allowing the duplication of copyrighted materials that doesn't hurt a work's commercial value. Lawmakers argue that protections aren't needed because the bill calls for the prosecution only of those who "willfully" violate copyrights. Their argument overlooks all the people who know they're using copyrighted material but do so without criminal intent: the researchers, students, writers and Web surfers who duplicate copyrighted materials as a way to communicate. Unless a clear exemption is written into law, all risk becoming targets for overly aggressive prosecutors. There are compelling reasons to revise copyright laws for our digital age. But without guaranteeing researchers the same protections on line as they have off, Congress risks limiting the Internet's legitimate uses. ###

GLAAD report on filtering software: "Access Denied"
by Declan McCullagh 17 Dec '03

17 Dec '03

======= Date: Tue, 2 Dec 1997 14:16:07 -0500 From: Cathy Renna <CathyR(a)twbg.com> To: "'Declan McCullagh'" <declan(a)well.com> Hi Declan-- I am greatly appreciating your comments and articles about the summit (Loren Javier and I are attending right now. Here is our release about the filtering software report. Cathy Renna Washington, DC Media Resource Center Gay & Lesbian Alliance Against Defamation (GLAAD) (202) 986-1360 fax: (202) 667-0902 renna(a)glaad.org VISIT THE GLAAD WEB SITE AT http://www.glaad.org!

(800) 946-4646 pin# 1423527 e-mail: tracey(a)glaad.org GLAAD RELEASES GROUNDBREAKING INTERNET FILTERING SOFTWARE REPORT NATION'S ONLY LESBIAN & GAY MEDIA ADVOCACY GROUP EXAMINES COMPLEX ISSUES IN "ACCESS DENIED" NEW YORK, TUESDAY, DECEMBER 2, 1997-The Gay & Lesbian Alliance Against Defamation (GLAAD) today announced from the historic Internet Summit the release of their comprehensive and groundbreaking report on Internet Filtering Software and ratings systems, "Access Denied: The Impact of Internet Filtering Software on the Lesbian and Gay Community." In the wake of the Communications Decency Act decision, Reno v. ACLU, and with the Internet Summit: Focus on Children being held through tomorrow in the nation's capital, GLAAD has completed an exhaustive survey of how Internet filtering software, and future proposed ratings systems affect the lesbian and gay community. The findings mark the first time a lesbian and gay media advocacy organization has produced research and analysis of such depth on the issue of Internet access. "The majority of software currently on the market, as well as new products in development, place informational Web sites serving the lesbian, gay, bisexual and transgender community in the same categories as sexually explicit sites," the executive summary reports. "The software developers are either unable or unwilling to consider that information about sexual orientation and identity (e.g., a gay square dancing site) has nothing to do with sexual behavior, and everything to do with culture and identity." "Access Denied" contains sections analyzing the legal, political and social implications of enforced invisibility on the Web. It also includes overviews written by members of groups such as Gay and Lesbian Parents Coalition International (GLPCI) and Peacefire (an entirely youth-run cyberliberties group), as well as testimonials from lesbian, gay, bisexual and transgender youth, who, as seen in the report, are those most directly affected by the lack of access to important information via the Web or Internet newsgroups. "I urge everyone who uses the Interent to read this report, and learn the troubling implications of the widespread use of filtering software," states Joan M. Garry, GLAAD Executive Director. "As a mother, I can assure you that while GLAAD has examined the disturbing aspects of filtering, we never lost sight of the youngest users of the Internet-our children. Whether it is through the testimonials of lesbian and gay youth, or an essay written by a gay father, the voices in this report must be heard now-perhaps soon, they will be much harder to find." The report also includes a thorough review of the currently available software, ratings systems and search engines, recommendations for industry leaders on how to make the Internet both friendly and fair, as well as a proposal for a future ratings system, FAIRsite, which would measure the accessibility and accuracy of various ratings systems and software. GLAAD is a national organization that promotes fair, accurate and inclusive representation of individuals and events in the media as a means of combating homophobia and all forms of discrimination based on sexual orientation or identity. -30-

To establish a nym only through one way communication? I can think of a couple of ways this could be implemented. You could either allow the user to select an e-mail address to use, then do an nslookup to verify that the domain does not exist, or else choose a domain that's actually nothing but a bit bucket. The cleanest implementation might be to create a "bitbucket.efga.org", alias all incoming mail (except for perhaps "postmaster") to /dev/null, then assign non-replyable 'nyms off of that. That would eliminate the need for managing reply blocks and confirmation cookies. This is much more preferable to these people you see who post with a From: address of "nobody(a)nowhere.com", probably not realizing that nowhere.com is actually a real domain. But implementing such a server is still a lot more work than simply allowing From: headers to be pasted and allowing source blocking for anyone who is worried about being the victim of abuse of such a scheme. - --- Finger <comsec(a)nym.alias.net> for PGP public key (Key ID=19BE8B0D) -----BEGIN PGP SIGNATURE----- Version: 2.6.3i Charset: noconv iQEVAwUBNIRgZwbp0h8ZvosNAQGC7gf+PRUB+6Zuxns3E+BWZoM3kkzn4MD9vcip 1MvQRFRvTTdvGM4vFySYcZByv7SQJdIiVZItyzMe4qMz+Ft/xpbWUYmz3mOpws9H RW3sbsFywNzp4pCxolKhMJ8QTQI/tHb3CHT6thHkbgjpzr4bJlL6trLKn+btY2d/ MdNq61oPCTq4YYdj9kC8WebngjfJZOvcvQhX1OLtUaagrpL8DiGxivGSz/Rdl6ZC Yr8m8m0V/l6WA4HG3ZKTDoBz6OBxI7VROZRZdJkCRHKgScQP9/4+UYnSbew1rAhE apoUG3Ds7kiIUoZ9gLz01sYvRRaWelIjIZLp+RfnMPvtwXexP2uA8Q== =+uAL -----END PGP SIGNATURE-----

This guy has the IQ of a turnip... relevant to anon remailers & society thread... Tuesday December 2 12:07 PM EST Hate e-mail case to be retried SANTA ANA, Calif., Dec. 2 (UPI) _ Saying the case has national importance, federal prosecutors will retry a 20-year-old man accused of sending threatening electronic mail to Asian students at UC Irvine. Prosecutors announced their decision while opposing a bail request for Richard Machado of Los Angeles, the first person in the United States to be tried on charges of committing a hate crime over the Internet. His first trial on those charges ended with a deadlocked jury in November. Jurors voted 9 to 3 to acquit the former UC Irvine student. Assistant U.S. Attorney Michael Genaco told Judge Alicemarie H. Stotler that it is important that the case be resolved because other similar cases are certain to occur. Stotler denied bail for Machado, noting that he fled to Mexico when he was first charged.

A Netly Thanksgiving (guess I should have posted this earlier)

MacOS 8. A Supreme Court that supports free speech online. DVD. Cable companies offering 400 Kbit/sec Net-connections. But we're also grateful to the personalities who made this year an unforgettable one: Heaven's Gate: A special Netly thanks to these suicide cultists for providing us with seemingly unlimited article fodder. From the blinking red alert headline of their celestial home page to the computer-generated painting of a resident of the kingdom of heaven, their web site was a treasure trove for journalists. Buried in the invisible space at the bottom of the home page were hundreds of hidden words: UFO, space alien, extraterrestrial, misinformation, second coming, end times, alien abductions, Yoda, Yoga. Wonderful stuff. Louis Freeh: The butt of a thousand jokes on the Net ("Freedom isn't Freeh"), the FBI director emerged this year as the arch-enemy of strong encryption. We had worried that Deputy Attorney General Jamie Gorelick's departure might mean fewer good stories from the Justice Department.

Censorware Summit 2.0, from The Netly News
by Declan McCullagh 17 Dec '03

[For details on some of the proposals presented, read the full article. --Declan] ============ http://cgi.pathfinder.com/netly/opinion/0,1042,1608,00.html The Netly News Network (http://netlynews.com/) December 2, 1997 Censorware Summit 2.0 by Declan McCullagh (declan(a)well.com) If there's one political controversy that promises never to die, it's sex and the Net. There seems to be something about the combination of children and cyberporn that makes otherwise levelheaded adults more than a little worried -- and even a little irrational. Enter the politicans, always happy to pacify parents with soothing rhetoric. Vice President Al Gore is scheduled to speak this morning at a two-day summit dedicated to protecting kids online. Of course, the Communications Decency Act's backers had claimed that that particularly nasty law (which the Supreme Court found to be unconstitutional) did just that. They were joined by the White House, which two years ago said "the President firmly supports the Communications Decency Act" to "regulate the exposure of children to computer pornography." This time, however, the White House would like to avoid the same embarrassing mistakes -- and, perhaps more importantly, would like to avoid pissing off high tech firms that could be hefty campaign contributors to Al Gore 2000. Instead of endorsing new federal legislation, the Clinton administration says it'll oppose it as long as industry regulates itself.

PGP signing a post is a lot like the new anti-counterfeiting measures in US currency, only a lot more effective. But if some bozo decides to start printing up three dollar bills with a portrait of Mickey Mouse, and others are foolish enough to accept them, what are you going to do? It's hard to protect people from their own stupidity. I'd contend that a $3 bill isn't even a counterfeit or forgery, since there is not genuine equivalent which it seeks to fraudulently duplicate. Maybe it's time that the brain-dead software that mindlessly harvests e-mail addresses from the net was shut down.

For one thing, to identify posts as originating from one's pseudonym, which *MIGHT* be a "real" e-mail address.

It has more to do with the ability > to post to an mlm group with someone elses' email address. Oh, and btw, if a > NETCOM customer is caught doing this, his/her account is terminated. The key word there is "caught", and then you'd have to convince Netcom to actually do something about it. It is my understanding that spammers routinely utilize Netcom's OPEN SMTP SERVERS to send out their spam, using whatever From: field they wish, and Netcom doesn't seem to care. Anyone using those same servers to send mail to a mail2news gateway could forge someone's name and e-mail address to a Usenet post, couldn't they? Also, even if a complaint to Netcom got an individual account shut down, that wouldn't stop some other Netcom user from doing the same thing, nor would it stop the first Netcom user from opening another account under a phony name and repeating the process, or even doing it from a non-Netcom account. So if my e-mail address were being forged via Netcom, would they be able to source-block it as the remailers currently can do? If not, doesn't your own ISP have a bigger abuse potential than the remailer net? > AGAIN IT'S NOT FORGERY THAT'S A PROBLEM.

Transforming Defense
by John Young 17 Dec '03

17 Dec '03

The National Defense Panel presented yesterday to the Secretary of Defense its 95-page report on the future of US defense: "Transforming Defense: National Security in the 21st Century." It's available in PDF format at: http://www.dtic.mil/ndp/FullDoc.pdf (386K) The report proposes an impressive 30-year overhaul for the military, with a recommendation that the two-major-wars strategy be replaced with that of preparing for one major war and a host of more limited defenses overseas and at home to combat enemies who will not challenge superior conventional armaments but will utilize "asymmetrical" NBC weapons, terrorism, information warfare. We've converted the Executive Summary to HTML: http://jya.com/ndp-pr.htm And a section on "Homeland Defense" which proposes a role for military forces to "protect against all enemies foreign and domestic" by providing intelligence, training, equipment and other aid to justice and law enforcement. http://jya.com/home-def.htm As noted in the NYT today, the report asks for a shakeup in intelligence, with renewed emphasis on training human spies to compensate for what technology cannot do. Along that line, the NYT also reports today on a huge Libyan deeply-buried pipeline system under construction which is suspected of being a distribution system for troops and equipment as well as CB weapons, placed underground to escape satellite spies. The report is based on descriptions of engineers and corporations working on the project. One feature of the NDP report, as well as other closed defense panel meetings, is the need for weapons to attack underground structures -- like those vast catcombs in Lybia and North Korea, and the US for that matter -- Cheyenne Mountain is still being re-hardened regularly, and its electronics re-Tempested, not that the local skinheads will not find a way to hack the bunker as trusted EEs and sys admins.

Please consider the following suggestions >if you like, or feel free to ignore them. Your suggestions were very helpful. Thank you for making them! I'm calling the latest version "Cantsin Protocol No.2" and its identifying number is "25BA1A9F5B9010DD8C752EDE887E9AF3". It is similar to Cantsin Protocol No. 1, but the bug with the hash of the public key is fixed. Instead of concatenating the values p, g, and y, you concatenate "p:<p> g:<g> y:<y>" and compute the hash. p, g, and y should be represented as ASCII hexadecimal digits without leading 0s. The hashes should now be correct SHA1 hashes. >One problem with signatures which have no indication at the top is >that two passes over the data are necessary: the first to scan and >find the start-of-signature indicator, and another to go back and >calculate the hash. Signatures such as S/MIME and PGP have enough >information at the top of the signed message to allow one pass >processing. My thinking on this is that passes are cheap these days. I want the signature to be unobtrusive which probably can't be done if only one pass is required. Incidentally, a nice feature of these signatures is that they can be moved around in the file just by changing the offset. You don't need to control the secret key to do it. >> The first line is "16A5942B6EED349ECF4594C784DFD177 [Cantsin >> Protocol No. 1]".

This could throw off an automated signature checker. The signature checker should ignore bad or incomplete signatures. I would consider this to be a bug in the software and not a bug in the protocol. A bad signature simply lacks meaning and an error message need not be reported. That might seem a little callous, but actually it's how we should regard signatures. The current model seems to be "computer, check the signature on this file and tell me if it's good", whereas the correct (in my view) model is, "computer, extract all of the material from this file which is properly signed and throw out the rest." (Of course, you could imagine a smart editor which highlighted the areas of a document which were signed by various parties. It seems a little early to implement this.) If it's not authenticated, you shouldn't even look at it. I've taken to putting the To: and Subject: header lines at the bottom of my messages for this purpose. There's really no need to keep any of the header fields. The header fields can be put at the end just as unambiguously as at the beginning, but at the end they can be signed. >> The second line in the signature is an SHA1 hash of the public key. >> The hash is computed on the concatenation of the hexadecimal ASCII >> forms of p, g, and y respectively.

Strictly speaking it's there to save space. If we put the public key components in every signature it wouldn't be much harder for the key management software to compute a hash on them somehow. This does not have to be standardized. >This has a mild denial of service attack. Someone else could create >a key with different boundaries between p, g, and y but which would >create the same string as this concatenation, and therefore the same >hash.

I knew about this problem, but I couldn't remember exactly how it worked. So I said, "Monty, let's not be dumb like those PGP guys. Let's concatenate the keys together and compute the hash. Nobody will ever..." Thank you very much for pointing this out. >> The fourth line contains an offset and a length to specify the area >> of the text which is signed.

Probably CR/LF would be preferable for the line >endings as that is a widely used internet standard as well as being >common on windows. My feeling on this is that this is outside the scope of a signature protocol. The protocol should not make any assumptions about what is being signed nor should it modify what is being signed. I use LF to terminate lines and would recommend this to others, but it is not part of the Cantsin Protocol No. 2 specification. In any event, if we must put in patches to handle the poor fidelity of electronic mail, the patches should go in afterwards. When a signature checking program finds ">From" it should replace it with "From" and see if it can get the right checksum. Likewise, it should try the various line endings until it gets a match. There can't be more than about 12 variants, so this shouldn't create an onerous burden on the machine. (And, I suppose, it would be possible to add a field after the length or after the hash which made a suggestion about the line ending.) >> You also need to be able to compute SHA1 hashes.

Another great suggestion. The hashes should be correct now. Incidentally, in another thread I've been talking about partial signatures. The code above is an example of where this would be useful. In some countries we are not allowed to express ourselves freely without persecution. If I wanted to provably quote somebody who included forbidden ideas in their message, it wouldn't be possible without partial signatures. >> El Gamal is simple enough that the signature on this message can be >> checked using standard Unix tools such as dc version 1.1.

DSS has a shorter signature. This might be a good thing to add to a later Cantsin Protocol. >There are some subtleties to choosing El Gamal keys, but with the >2048 bit values you have chosen you are pretty safe. Schneier doesn't mention this, although presumably this information will show up in one of his references. Do you know offhand of a published source which covers this? >Also, you can't really justify using 2048 bit keys when your hash is >only 160 bits. The hash becomes the weak link for keys beyond about >1024 bits, and unless you use a stronger hash your key strength is >misleading. This is why DSS is only specified up to 1024 bits. This is just intuition, isn't it? Since we really don't know how hard it is to factor it seems hard to claim we know the ratio of difficulty between breaking SHA1 and El Gamal. Factoring could be broken before SHA1. Not that any great science was applied to the choice of a 2048 bit prime, it just seemed like a good size. ;-) Also, I think it is a mistake for people to communicate the strength of a system by choosing various key lengths based on general popular views. It's probably better to say "I estimate this system requires at least 2^x operations to break." We've seen this with people choosing short keys so nobody will get the idea that it is secure. This just seems all wrong to me. The key length is only one way in which a key could be insecure. Monty Cantsin's authentication key, for example, is not kept very securely. But, the way to communicate that is to say "this key is not kept all that securely." However, in Cantsin Protocol No. 2 the size of the prime chosen is completely unspecified. There doesn't seem to be a reason to restrict the choice other people will make regarding the length of the prime. I could imagine choosing a short key for control over a semi-persistent identity. The advantage is that you can claim somebody else brute forced the key for statements you wish to repudiate. Similarly, I could imagine choosing an obnoxiously long key to make it hard for people who don't have super fast machines to associate with you.

Standard doctrine, but I no longer believe it is sound. We've been at it for years now. Are the masses using crypto? I didn't think so. It's a waste of time to sell to people who think they "have nothing to hide". Even if they were using crypto, they would accept snoopware if it were accompanied with the right media programming. Which means that instead of proselytizing, it's probably better to develop systems which we can use which are expensive-to-impossible to thwart even in hostile environments. There's no need to turn people away, of course, but begging people to help themselves is a poor investment.

Monty Cantsin has provided us >a moving description of the painful deaths of the children in Waco. >Will dying of asphyxiation under pressure too great even to draw a >breath be any easier? You've hit upon something interesting here, Anonymous. Let's consider three groups of children. 1. ~100,000 children harmed in Iraq. 2. ~40 children harmed in Oklahoma City. 3. ~20 children harmed outside Waco. Of these three groups, the third upsets me the most. Why? There are several factors. One is the extent to which the people committing the actions claim to represent me. It is often claimed and widely believed that the Federal government is acting as a representative for and is answerable to the American people. (Allow Monty Cantsin a hollow laugh here.) That being the case, Waco is far more upsetting than Oklahoma City in this regard because McVeigh (or whomever) is not thought to represent a sizeable proportion of the American public. In the case of Iraq, this factor raises my concern well above other places in the world where children are mistreated. Of the three groups of victims, I identify most strongly with the people in Waco. While not strongly religious myself, I respect people who have unusual beliefs and stick to them. And I have sympathy for those who might live in unusual ways. While I share a culture with the victims in Oklahoma City, in general we would have little to say to each other. I don't know anything about people in Iraq. This factor probably governs my feelings on the matter most strongly. The motivations of the people committing the acts are important. I do not believe that McVeigh (accepting the standard paradigm) meant to kill children. He certainly meant to kill people who had no involvement with Waco. I do not approve of his choice. I would maybe even kill somebody to prevent it from happening. But, one feels differently when children die more or less by accident than when it is cold bloodedly premeditated. In the case of Iraq, it is extremely hard to justify killing kids for their oil. The provocation that leads to an act must also be considered. I am extremely sympathetic with McVeigh's desire to do something about Waco, even though I do things less violent and (hopefully) more effective. There was no reason whatsoever for the Waco crime to be committed, likewise people living in the Middle East have not really committed any provocative act more serious than having oil on their land. The mob mentality that seems to have gripped the United States during the Waco atrocity has a particular horror which is absent in the case of Oklahoma City and, right now anyway, mostly absent with Iraq. The blatant misrepresentation of what was occurring and the degree to which people were compliant with it is shocking. There was no serious attempt to investigate the motivation behind the raid, or even what was actually occurring from day to day. The aftermath was even more horrifying. The government attacks and murders ~80 innocent people in the most brutal way for no identifiable reason. And all anybody can seem to do is to try to protect the establishment, instead of finding out exactly what happened, instead of charging the criminals who perpetrated the horror, instead of taking the necessary actions to make sure nothing like this will ever be done again by the Federal government, and instead of telling the truth. The implications of the three situations create varying degrees of alarm. I do not expect to see many more bombings. Bombs are nothing new. They've been around for over 100 years and they are a manageable problem. Every few decades there's been a big explosion. It is unlikely McVeigh will do something like this again. In the case of Iraq, I'm used to governments behaving this way and I do not see it directly affecting me very soon. (Perhaps this is a bit insensitive.) Waco, however, is quite another matter. When you watch the footage it gives you the creeps because what is being reported belongs in the 1940s and the people should be speaking German. Instead, everybody speaks English with an American accent and it's happening right now. When you see an FBI agent justify what happened on the grounds that he goes to a "normal" church and has a "normal" family, and when you see other officials state that they wanted to harm the children to encourage the parents to turn themselves in, the implications are that we have a very serious problem that will not go away by itself. Finally, in the case of Waco, the people in charge had all the time in the world to think very carefully about what they were doing. They apparently decided to kill everybody they could, including particular children whose names they knew, whose pictures they had seen, and some of whom they may have even spoken to on the telephone. This really is hard for me to understand. I can't imagine what kind of person can do something like this. This horror is particular to Waco. In the case of McVeigh and the people making policy regarding Iraq, the victims are at least anonymous.

There is really no reason to use it. It seems to be the same as the jam remailer which is free. I had hoped to use it as an exit remailer, but even that is a loss as it apparently uses cracker (?) for that purpose. What we did learn is that it isn't that hard to set up a remailer to accept ecash. I doubt we've learned much about the market potential.

Ecash accepting remailers should offer perks which are not generally available, or just offer a faster more reliable service to paying customers. For example, free messages are delayed 90 minutes while paid messages are sent immediately, modulo some details like mixing.

Re: CDT and the Threat of Gov't Intervention
by Declan McCullagh 17 Dec '03

17 Dec '03

Besides demonstrating that cyberporn is a topic that will never disappear, the Kids and the Net summit has highlighted the tensions between the different types of Net-advocacy groups here in Washington. The civil liberties groups (ACLU, EPIC, EFF, CPSR), and journalism, publishers, and media groups have lined up on one side [http://www.ifea.org/] saying the government shouldn't pressure the Internet to self-censor (or be censored by the Feds). They held a counter-summit press conference yesterday. Even the libertarian Cato Institute is in this corner. On the other side, the Center for Democracy and Technology [http://www.cdt.org/] is participating in the summit along with antiporn groups, high tech firms, and "censorware" vendors. CDT says that the Net needs to self-regulate or face the wrath of the U.S. Congress. (Folks at CDT generally take pro-industry positions and have been involved in many compromises in the past: wiretapping, "harmful to minors," and jail time for use of encryption in a crime.) CDT, however, has called for the development of multiple rating systems. You could easily tell the difference between the two outlooks today. ACLU associate director Barry Steinhardt and CDT director Jerry Berman debated this afternoon. "If we sit back and we offer nothing... that's not a solution for the American public," Berman said. He said that CDT is "looking to balance free speech rights" with other values. -Declan At 11:04 -0400 12/2/97, Michael Sims wrote: >What "they" are saying: > >SF Chronicle: > >"Internet Self-Regulation Draws Wide Praise But advocates for free >speech call for extreme caution > >Jon Swartz, Chronicle Staff Writer > > Civil libertarians and porn peddlers yesterday praised the Internet >industry's attempt at sweeping self-regulation to keep smut out of >the hands of children and the government at arms' length. ..." > > >Civil libertarians praised sweeping self-regulation, eh?

I can see the advertising campaign now: "Bank at Big Brother Bank, NA - have your eyes ripped out!" The device probably has trouble distinguishing between a mannikin with some real eyes and a real person. Conveniently for the robbers, the victim will be unable to identify anybody later. The plausibility of this threat model has a lot to do with whose eyes we're talking about. If they're your eyes, be my guest. It's probably safe. ;-) This is just one of the many risks of deployment of these technologies, but it's the one that makes even the most docile sheep pay attention. Consider the child implant issue.
