If you record - say - 5 of them and send them by 5 seperate couriers and xor them together to send the message, your enemy has to compromise etc 5 people. Or your enemy has to penetrate your site or your correspondent's site, and copy five CD-ROMs instead of one. CD-ROMs have one advantage: there's a lot of data. But that's not all good, because you *really* want to destroy any keying material you've ever used. I've heard People Who Know say that in the spook and government world, one-time pads are falling out of favor --- because their practical security isn't as good as a really high quality conventional cipher with a dynamically-negotiated session key. I repeat: *practical* security; your enemy isn't going to hit you or bribe you with a copy of Shannon's theorems.

From: James Hicks, <71332.747(a)compuserve.com> Well, a couple of nights ago I was sitting here using my modem, I had just finished perusing the C'punks list, when I heard about 5 shots ring out in the alley next to my home. A few lines of garbage zapped across the screen and then the modem was totally unresponsive. Well, I picked up the phone (another line); dead silence. [You guessed it. One of the bullets hit the phone line. ASCII armor was no defense]. Not wanting to go through the night totally out of contact with the rest of the world, I decided to place a call to the phone co. from a nearby neighbors place but decided to sit tight for a few minutes to foil traffic analysis (and give whoever it was running around out there in the dark with the gun a little time to move on). After the sun rose about 10 shell casings were actually found within a few feet of the line break (about 30 residences actually had service interrupted). And It's usually so quiet around here. My neighbor says that a policeman told him that local entrepreneurs will sometimes use fire guns into the air to signal potential customers that they are open for business.

For folks interested in ViaCrypt Use

From: IN%"71332.747(a)CompuServe.COM" "James Hicks" 18-DEC-1993 11:04:13.14 To: IN%"miniters(a)citadel.edu" "Syl Miniter" CC: Subj: ViaCrypt Syl, I saw your question on the Cypherpunks mail list. Recently Dave Barnhart, the ViaCrypt product manager (for Lemcon Systems) became active on Compuserve's Electronic Frontier Forum. The following is a statement he left in the forums message section. He appears more than willing (even eager) to answer questions about ViaCrypt and can be contacted at the addresses given in his message. James |>----------------------------------------------------------------------<| |PGP 2.x Key ID: F9A281 Fingerprint <F2A1A42B 67408691 5A6A2F0F C1104457>| |>----------------------------------------------------------------------<| *========================================================================* From: Dave Barnhart (ViaCrypt), 70275,1360 70275.1360(a)compuserve.com Date: Thu, Dec 2, 1993, 8:45:16 PM [PST] ViaCrypt is a division of a 17-year old company named Lemcom Systems. Lemcom Systems has traditionally produced IBM mainframe communication controllers and other network products. About 1989, we began producing a network product that used DES (That's about the only kind of encryption that IBM will admit exists). About 2 years ago, the ViaCrypt division was formed to develop products incorporating public key cryptography for the PC, UNIX, and workstation market. About 1 year ago, ViaCrypt sub-licensed the RSA patents from Public Key Partners (PKP). Late last summer (1993), we were introduced to Phil Zimmermann, author pf PGP. Phil expressed an interest in finding a way to commercially market PGP. Together with our law firm, one of the coutry's formost experts on intellectual property rights, we examined the terms of our PKP sub-license to determine if ViaCrypt could market a commercial version of PGP, and if so, under what conditions. At the same time, we also investigated obtaining a sub-license for the IDEA cipher from Ascom Tech AG in Switzerland. The opinion was that we could market PGP provided: 1) we substituted ViaCrypt-written RSA code for the existing RSA code in PGP. 2) we did not supply source code. So in late September we signed an agreement with Phil Zimmermann to market the commercial version of PGP, which we chose to call ViaCrypt PGP. Except for the RSA routines, a couple of bug-fixes provided by Phil, and a change in the "welcome banner", the code in ViaCrypt PGP is identical to that found in PGP 2.3a. This means that it is interoperable with PGP 2.3a. Except for the aforementioned changes, we made no other changes or additions to the PGP 2.3a source to produce ViaCrypt PGP 2.4 for MS-DOS. Why would you buy ViaCrypt PGP instead of using the 'freeware' PGP? First, many small businesses and large corporations have expressed a great deal of interest in using PGP, but have not done so because of the legal exposure from RSA. ViaCrypt PGP removes this problem. As for the individual, Dr Hugh Miller said it best on USENET, but I won't quote him here without his permission. Essentially, it's your chance to "stand up and be counted" on the subject of how you want your encryption. It's the best chance we may have to say: 1. "We don't like the rigid, hierarchical trust model in PEM", and: 2. "We don't want any system incorporating key escrow (a la clipper)" ViaCrypt PGP version 2.4 for MS-DOS is available from: ViaCrypt 2104 W. Peoria Ave Phoenix, AZ 85029 Phone (602) 944-0773 FAX (602) 943-2601 Internet: wk01965(a)worldlink.com Compuserve: 70304,41 Price: $99.98 (single user) $299.98 (five users) $824.98 (20 users) Plus $8.00 S & H, (and if you live in a small number of states, I can't remember which ones, they make us collect sales tax.) We intend to have ViaCrypt PGP available for just about every platform on the planet. We should be announcing the availability of ViaCrypt PGP for several UNIX platforms shortly. I hope to have MAC and Windows versions available some time in the second quarter of 1994. And I know it doesn't make for a great story, but at the CSI Computer Security Conference in Anaheim a month ago, Phil Zimmermann was in our booth (we asked him to come). Jim Bidzos was at the same conference, making a presentation. There were no bloody brawls in the hallway, no shouting matches, I don't think the two even encountered each other. The rest of the folks at the RSA booth stopped by, and were actually quite cordial. ho hum. I apologize for the length of this message, but I hope it answers everyone's questions. If not, ask away, or feel free to contact me at ViaCrypt. (If you call ViaCrypt with questions, I'm the one you'll probably talk to, by the way.)

Stego Help Requested...
by Jim choate 17 Dec '03

17 Dec '03

Hi everyone, As some of you are aware I have been looking at stego, in particular trying to calculate the maximum feasible message to insert in a given image. I have determined some techniques that help predict this ratio. In the process of testing them I got side-tracked into converting images to other format (RGB > HSV in this case). Since these are linear but not equaly scaled there is some range alteration in the conversion process. It appears that if a RGB image is holding a image it converts to HSV differently and is thus easy to test for. I am in need of some additional data and basiclly clueless where to find it. The data falls into one of the following ways: > source of images in both HSV and RGB format > pd or shareware software that will convert mathematicaly > access to a video color registration set to generate the above database Any help in locating any one of these would be greatly appreciated. Have a Merry Christmas! Ravage Black Leather Monster

My Party NOT!
by Harry Shapiro 17 Dec '03

17 Dec '03

Hi, A member of this list (Edgar Swank) recently posted a message to this list providing details of a private party I am holding. That message should not have been forwarded here. The party in question is, as I mention above, private and is not open to the public nor the membership of the Cypherpunks list. (This is most due to the VERY limited size of the "party room.") I am posting this message for anyone who felt that message was an open invitation to join my party and to indicate that was not the case. The party guest list is limited to members of the Extropians list who have RSVPed, others will not be admitted. /hawk -- Harry S.

data point re. Inman
by an58933＠anon.penet.fi 17 Dec '03

17 Dec '03

I have (sort of ) worked for Inman twice. He is currently serving as a director for the company which employs me. Recently, the company has launched a campaign to coerce employees to sign agreements relinquishing their rights to sue the company and its officers if the employees are willfully injured, sexually harrassed, etc. I have been told that this was done at the request of the board; certainly I would expect board review on something like this. I don't know what position Adm. Inman took, but this still reveals a bit about the corporate culture he contributes to. ------------------------------------------------------------------------- To find out more about the anon service, send mail to help(a)anon.penet.fi.
