Distributed "Family" of processors
by PMARKS＠VAX1.UMKC.EDU 17 Dec '03

17 Dec '03

I recognized the basic schema in the following from the history of the French Resistance movement. The idea is for critical information to be held in separate "cells" each of which knows only enough to inteact with the others, but not enough to compromise the entire net. ************************************************************************** Consider three sets of code in three computers that constitutes a "Family"(the whole program). "Grandpa" talks to "Pa". "Pa" then talks "Son". "Son" then talks to "Grandpa". Each "Family" member closely monitors its cup clock & if its expected message is not received on time - it suicides! Capture "Pa" & in seconds, "Grandpa" & "Son" take their own lives! That is to say, they scramble certain essential parts of themselves including cryptographic sections. ************************************************************************** In any covert activity, many conditions will lead to a mission abort. This is largely due to the paranoid nature of the activity and the low level of trust in others neccessitated by said activity. If even one aspect seems "wrong" the meeting, transmission, transfer, trade, whatever, is called off. No offense intended, and ususally none taken. When you are trying to be covert, everyone fears compromise. A computer system so paranoid that it swallows a poison-pill whenever it suspects unauthorized tampering (read: investigation) would be fairly secure, but unreliable. ***Many*** conditions would trigger the "trip-wire" mech- anisms so the system would have to have a high order of built-in redundency. What it always boils down to is, "who do you **really** trust?". Or, boy was my face red when I found out I vouched for my best friend's public key only to find out that he worked for the NSA. (Think it doesn't happen? HUMINT will tell you much more than Signal Analysis ever will.)

Clipper LEAF Holes?
by Mike Ingle 17 Dec '03

17 Dec '03

As I understand the Clipper/Capstone LEAF, it works like this: Take 80-bit session key. Encrypt with device-unique key. Add 32-bit serial number and 16-bit checksum. Encrypt resulting 128-bit packet with family key. One of the EES chips, the type designed for cellular and other phones, operates in "1-bit CFB mode". This would seem to indicate that it is a straight-thru device - that the data input and output rates are the same. So the LEAF is only sent once; it is not repeated throughout the output. The user is forced to send a valid LEAF because the receiving chip will not set up without receiving a LEAF. But how does the receiving chip check to see if the LEAF is valid? The obvious way is to decrypt it with the family key, and then verify the checksum. But EES chips for different countries will have different family keys. So if an American EES chip sends a LEAF to a foreign one, how does the foreign one verify the LEAF? Even if the receiver can decrypt the first level of the LEAF and examine the checksum, it doesn't have your device-unique key, so it cannot check to see if the session key in the LEAF is the same session key that you sent to it. So it would seem that any valid LEAF would work, even if it is not the one for the current session key. Am I missing something in the Clipper design which prevents this? --- Mike

You will have to read the file README.MPJ which tells the name of a "secret" directory to cd to (which changes every time). Then look at pgp_tools/pgptl*. Hal

your Clipper video testimony wanted
by Stanton McCandlish 17 Dec '03

17 Dec '03

Forwarded message: From: blogan(a)crash.cts.com (Barry Logan) Subject: Re: vid testimony Date: Thu, 21 Apr 1994 11:51:17 -0800 ****** P A P E R T I G E R T V S O U T H W E S T ******* For Immediate Release 4.20.94 *Distrubute Widely* This is a request for submissions of video testimony regarding Clipper. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The public is increasingly becoming aware of the Clipper. Hearings are scheduled to held on April 27 and May 3, 1994 by Sen. Patrick Leahy's (D-VT), of the Senate Judiciary's Technology and the Law Subcommittee, the subject of which will be the Clipper initiative and the FBI's draft Digital Telephony surveillance bill. Momentum is building, get involved. Unless the conquest of cyberspace goes unchallenged by the public-at-large, First and Fourth Amendment rights will be abrogated in a "fait accompli" out-of-sight of democratic processes. This is a battle that cannot be won if fought solely in cyberspace. The implementation of draconian measures calls for innovative counter measures. We propose to take arguments against the Clipper proposal to the public with a video. Fighting with the traditional weapons of mass media will get the attention of the wider net-disinterested audience (most of whom will intersect with the net in the future), than relying on the net alone to conjure the necessary outcry to make Clipper an issue of public scrutiny. We need your collected clips to put together a composite argument. It will be distributed to public access television stations, key legislators, and also be made available to the general public. Submission guidelines: - DEADLINE MAY 8TH ~~~~~~~~~~~~~~~~~~~~~ -Send us a video of you containing your most cogent thoughts and passionate statement regarding Clipper. -Please limit your comments to privacy issues in general and Clipper in particular. -Send original tapes (we'll return them) in any format, 8mm, Hi8, VHS. ~~~~~~~~ Hi8 is the best. -Because of both the nature of video and the nature Clipper, guerrilla theater is encouraged. -Submissions of arguments in favor of Clipper will also be considered for inclusion. -Contributions from outside the U.S. are welcome. -Suggestions about content and/or format welcome. -Please send your video as soon as possible, but no later than May 8th for consideration. Information about Paper Tiger: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Paper Tiger TV is a non-profit volunteer collective based in Manhattan, with working groups in San Diego (PTTV Tiger South West) and San Francisco (PTTV West). Paper Tiger TV produces 30 minute programs shown weekly on public access cable TV and distributed to cable stations, colleges and libraries across the country. The collective has been working for nine years with critical readings on many areas of cultural production including advertisement, TV, films, mainstream publications and cultural events. Although there is no confirmation, it is likely that the finished tape will be uplinked by Deep Dish TV: an association of community and independent producers, public access and cable programmers; a national, alternative satellite network with multi-racial, multi-regional representation producing and distributing television that has a point of view. FEARLESS TV!! We hope that our shows will inspire, educate and empower the political movements that we are a part of. Mail your tapes to: VIEWING HABITS 3270 MT.AACHEN AVE. SAN DIEGO, CA 92111 We are including Herb Sciller's "Plunge into cyberspace". Well known lefty media critic and guru of our collective. This is a historic moment, don't blow it. Make history, make video.

Ok, Let me respond 1)I live in this kind of neighborhood at home when I'm not at school. That's right, I live in West Oakland, California. I was born and raised in the inner city. Don't tell me how these places are, don't tell me how they're run, don't tell me how dangerous they are. I've lived it. Have you? All you know is what you see on the news, on the television shows, and what is portrayed in mass media. 2)I know the value of a gun in this environment. I know how many times our home has been kept safe because my father has been willing to wield a gun against either intruders or against 'undersireable' characters coming around(read drug dealers, crack heads, you name it). Our part of the block has a reputation for not being somewhere for these pepole to hang out because my father and our neighbors have taken a stand against such scum. 3)Not everyone who lives in these neighborhoods is bad simply as a result of their economic conditions. We don't want these people around any more than you people do in your neighborhoods. It just happens, and I know this for a fact, that it takes Oakland Police(OPD) a lot longer to respond when we call them, than when people in Skyline(a rich white neighborhood) call them. 4)My family has not broken any law simply by trying to protect ourselves. There is no way in hell that the police can be everywhere at once, even if they are as efficient as you in the 'burbs seem to think they are, keeping out and harassing all the minorties that come your way. Until they get there, the only way we can protect ourselves is with our guns. We havne't broken any laws, we're not the ones who have severed our contract with society by choosing to live outside of it, its not us, its the people who prey upon us in our homes and in our schools, and it is not us who should lose our rights, but them. By simply lumping us in with them by sheer virtue of where we live and how much we earn is not only sheer folly but is also classist. 5)Yes we worry about the rights of the accused. I do. I've been arrested and harassed when the only crime that I committed was being in the wrong place at the wrong time, and not having the right skin color. Yes, I worry about those rights, because for me, it might be that one day, that it is I who is on trial, it is I whose rights are being questioned, and it is I who wants my day in court, and unless we protect the rights of the accused, even if they don't look like us, it reaps a beneficial result to society as a whole. Thomas More in the movie _Man for All Seasons_ makes an excellent point when he asks young Will, if he would cut down all the laws in England to catch the devil. When Will responds in the affirmative, More asks him, "And what would you do when the winds rage about you?" You see, if you don't protect the rights of the accused today, there might come a day when you're in their shoes and you'll wish that you still had those rights--remember the 5th amendment? The 4th's prohibitions against unreasonable seach and siezures? What about the 14th's due process clause? It is the rule of law, not of decree that makes this nation great, and there's no way in hell, I'm going to sit idly by and watch this nation become an autocracy simply because some people in suburbia decided that it would be easier to do away with the rights of the accused in their racist, xenophobic fears. Any comments? Ben.

It's very flexible and you can get access for very reasonable amounts of money (even for a server). The software's free, the net is huge, etc...

Most systems/people on the Internet are not subsidized. This is well known. The critical mass of users has obviated the need for it. I've been grappling with what features I'd like in the perfect communications / BBS / Internet / online system. Does anyone have strong opinions about which features are important? For instance: I find that my Unix Internet mail/news tools are an order of magnitude more efficient than any BBS message base reader I've ever encountered. sdw -- Stephen D.
