TEMPEST Defenses and average Van Eck Gear...
by nobody＠shell.portal.com 17 Dec '03

17 Dec '03

Hi All.... #1 using personal countermeasures against emanation eavesdropping IS defnitely NOT illegal. #2 So few people have actual experience with Van Eck gear either the ConsumerTronics Model or the Pk Electronics German Device or the version made by a firm in england. First of all Van Eck Monitor Eavesdropping seems to be a deeply shrouded subject even for most engineers and for most c-punks. Its basically a system for reconstruction of the sync signal for monitor radiation received with a standard tuning mechanism... It is VERY similar to various Pay TV Decode Schemes mentioned and detailed in Radio Electronics over the past several years combined with a Monitor and a high gain amplified antenna... VERY specific plans are available from consumertronics for 25.00. And protecting against Van Eck can be extensive as a faraday cage or a subtle as conductive Wallpaper. floors, doors and windows... it really depends on the economic resources of your adversary and how much of a bother you are... Sam Hill p.s. Careful monitor placement if you have A LOT(at least 50) computers/ monitors can use noise data displayed on non-critical monitors to mask emanations of a single monitor where critical data IS handled.. $3-25k spent by a firm on acquiring the technology for internal survey can save LOTS of money from having to Faraday Cage an Entire Data Center... As for eavesdropping on bus/circuit emanation we will take that up at another time

Nymalizer, politics on the list
by greg＠ideath.goldenbear.com 17 Dec '03

17 Dec '03

Will an input-oriented (recognition mode) Nymalizer be able to differentiate between the outputs of "actual people" (ha) and actual people as filtered through output-oriented (generation mode) Nymalizers? After all, once we discover that username 'x' posts using LOTS of CAPITALIZED words and phunny SPELLINGS and so forth, it doesn't seem so hard to turn a Nymalizer into a filter which would create (or at least describe to a human creator) text which would fit that pattern .. I'm pleased to see that Perry now supports moving politics off the list; his posts do make me wonder if he's being spoofed, as he cheerfully participated in the econ-flames of a month ago. Still, I wholeheartedly support either him or the spoofer in their call to take the politics somewhere else. -- Greg Broiles greg(a)goldenbear.com Baked, not fried.

Private and Public
by Duncan Frissell 17 Dec '03

To: cypherpunks(a)toad.com A >the government: it protects us, provides free schools, etc etc, in A >exchange for which we have to pony up a fair share of our earnings. You should know that there are people out there who would use deadly force to resist government attempts to provide *their* children with free schools. To avoid a political argument which some may feel would be inappropriate for cypherpunks -- you should consider that social systems are dependent on the power relationships among individuals and groups in society. As technology changes, this balance of power changes. Social systems which depend upon the people being weak and the government strong, cannot survive an increase in the physical powers possessed by the people. This is a technological phenomenon. One of the public services that groups like cypherpunks can perform is to give both the rulers and the ruled some advance warning of the transformations that are on the horizon so that both groups can adjust their plans. Rather than debating whether or not the people owe the government information about themselves, you should argue about whether or not the government has the technological capability to discover information about people. In the absence of such capability, government "rights" to have the information are merely rhetoric. Duncan Frissell --- WinQwk 2.0b#1165

Re: ID of anonymous posters via word analysis?
by Matthew J Ghio 17 Dec '03

17 Dec '03

Just reading this list I'm sure it would be fairly clear that word analysis could be used to identify posters. Reread a few posts on the cypherpunks list. Note who spells out "government" and who abbreviates to "gov't". Some people consistently use one or the other. Count who uses "though" and who uses "tho". Also look at who refers to "anonymous posters" and who talks about "nyms". I think you will notice some definent patterns. Other possible word favoritisms: cypherpunks/c-punks cryptography/crypto cipher/encryption America/USA England/UK baud/bps DigiCash/digital cash Internet/"the net" information/info Mail/E-mail/Net-mail Just looking at the above list I'm sure some of you will realize how much you favor using certain terms, others probably without noticing it. Sorting by subject is possible too. Notice that there is only a certain group of users who consistently discuss DCnets. Another group consistently mentions the IRS, and taxes. A different group typically discusses anonymnity and anonymous postings. Others tend to avoid certain topics. Think about your own postings and realize what topics interest you most. I don't think it would be too hard to establish a "text fingerprint" of people based on what words they use. Maybe when I have some time I'll write a program to do it and see how many different patterns/styles I can identify. P.S. Also note the variations in text markings to express emphasis. Note who CAPITALIZES, *stars* _underscores_ or Capitalizes The First Letters.

No Subject

Re the Phiber Optik case. I understand that only vanilla, split-band modems (1200, 2400 baud) were tapped, on the analog loop. They were, and still are, common in the mundane telco world. Throw a bandpass filter on the upper half of the audio band, get the answer data. Throw a filter on the lower half, get the originate data. Much MUCH easier than tapping modern full-duplex full-band modems with echo cancellation and compression. I know some of the datacops involved, and I seriously doubt they have a clue about how to handle V.32 without help from the NSA, which DOES know how to intercept them. Of course, even if the modems had NSA-proof encryption built in, the victim could always intercept the decrypted data on the DTE connector... cracking is and will remain a risky and stupid thing to do...

Cyphergurus: Advice needed
by W. Kinney 17 Dec '03

17 Dec '03

-----BEGIN PGP SIGNED MESSAGE----- I'm writing a Macintosh encryption application (nearing completion), which, when it encrypts a file, changes its file type and creator so that the encryption program will be launch when the file is double-clicked. I have to save four pieces of information about the original plaintext: file type, creator, data fork length, and resource fork length. These are placed in a resource in the encrypted file. What I'd like to get opinions on is _should I encrypt this header information_, since its format will be known to an attacker and, in many cases, its contents easy to guess? My inclination is to leave it plaintext, since the worst that can happen if a file type is known is the same type of attack that would _always_ be possible with an encrypted header. Thanks to all with thoughts on the subject. -- Will -----BEGIN PGP SIGNATURE----- Version: 2.3 iQCVAgUBLN9hEPfv4TpIg2PxAQEZCwP9G2nysBI31CnD2UasTUHQb3itwc2S1juc TGJRvo5iB1WRFHwYwxyraae41Kf2Xsu6qiuHAQWEuvGhG4MyiZjXwZsE5FU9pxRR CV/pvSG4J/teXvJXv575Vr3lVxI6isDa4oZcMtv5rOS7ihIqF4ssuHnlOa6mHckU KW81MGB8nkQ= =cLCE -----END PGP SIGNATURE-----

Re: (fwd) Clipper and Tipper on Route 666
by Clark Reynard 17 Dec '03

I must say I had never considered the possibility that the Data Superhighway itself might be a scam; but it's an interesting possibility. With all the hideous legislative work they cribbed from the Bush clan, a former CIA chief; how surprised would you be to find that the Data Superhighway AND Clipper Chip proposals were intended to be enacted almost simultaneously; to rein in the Internet. Perhaps the spooks have, as we all know, been buying CD-ROMS and grepping 'em. It could be a conspiracy to establish complete government surveillance of all computer equipment. I may simply be being paranoid, here, but in political situations which smack of unlikely coincidence; one must occasionally ask the rhetorical question _Cui bono_? In this case, a number of people stand to benefit; and, oddly, the people seem to be predominantly in the government. I'm not entirely serious about this theory, and I do present it semi-satirically, as a perspicacious few may have noted; but perhaps the topic shall stir up a bit of debate. "Route 666." I like that. How does one get hold of Pat Robertson's people? And get him to think we're good Christian boys, so they'll do it? I think Pat's _already_ pissed about this Clipper thing, and he'd be happy to talk about evil liberal perfidy in the White House. Anyone have their FAX numbers and addresses? ---- Robert W. F.

Revisionist History of the US....:( (fwd)
by John Young 17 Dec '03

17 Dec '03

Responding to msg by ravage(a)bga.com (Jim choate) on Fri, 2 Sep 10:8 AM >Lesson 2 should be that the 'external' threat won't >last forever and at some point the real issues will >blow up to such an extent that the poplace will not be >concerned about external events because they are so >busy trying to stay alive and make a living. Yes. The external threat to the US has diminished, let's hope, to where some resources, human and material, can be applied to ways to make an advanced society serve its citizenry without resorting to fear of foreign boogies. The way that the surveillance satellite systems of the US and the USSR helped to reduce fear of military planners is instructive. This non-lethal technology, though expensive, made, and continues to make, accidental nuclear war less likely, and seems to me to be a great service to the world's population. Aggressive weapons systems may be similarly replaced by non-lethal technology as scientists and technologists are asked to device such apparatus. Fear of economic and social deprivation might also benefit from the talents of those who once produced the tools of the Cold War and hot regional conflicts you mention. Further, this list offers other ways to envision a society less dependent on the national security rubric of big Government, and may thereby support alternative local initiatives for economic and civil affairs. Kudos for this non-lethal work. John
