message splitting for better mixing?
by jim＠bilbo.suite.com 17 Dec '03

17 Dec '03

A variation of the many "send bogus messages through the remailer" ideas... The idea: 1) write sender-side code to split message into N parts and send each part through a different remailer chain. 2) decrypt the parts as they arrive as per normal encrypted remailer messages. 3) write receiver-side code to detect "a part" and stuff it in a file until the remaining related parts arrive. When all related parts have arrived, present the complete message to receiver. Why? To increase the number of "messages" flowing through the remailers to make traffic analysis more difficult. Comments welcome. Jim_Miller(a)suite.com

What kind of car? (Dodge?) I think it's an Oldsmobile of some kind. Possibly the owner's initial. I see that car often. If I ever run into its driver I'll have to remember to ask what the significance of the 68/'D' is. -----BEGIN PGP SIGNATURE----- Version: 2.3 iQBVAgUBLbs2xDSSmvXojb+5AQHH2QIAoqpSiFECrt1Wl7W19EnrW5lYOe5AbtgM bLPVjLyDTSdP2KqzDibKwk/9oS7dg66/PiIgnL6TtjuoRS4qqkeqPQ== =QSjv -----END PGP SIGNATURE----- Internet: mdbomber(a)w6yx.stanford.edu Matt Bartley GPS: 33 49' 117 48' PGP keys on finger and servers

Evidence, how did the cases the FCC brought turn out? If the network had used commercial radio licenses, how much more would it have cost them (per node; I have a vague idea of the size and power of a random Amateur Packet Radio node (in computer terms and cost))? Would this have given them greater immunity in prosecution? (Hmm.. if you're passing it on, you're broadcasting it? Could encryption tech be used to "enhance" APRN to give sysops "plausible deniability?" Phil

the #freedom channel
by Gary Jeffers 17 Dec '03

17 Dec '03

I spoke in an earlier post of the #freedom channel on the Internet chat. A brief description of #freedom. They interactively send messages to each other in code. The code is fast & they seem to be talking fluently to each other. This would seem to be an interesting matter to Cypherpunks. I have been asked for more info. on the #freedom channel. I don't know anymore than I've already talked about except that they are not a hidden or invite only channel. Of course, when you talk to them you are ignored. Apparently, they ignore other people because their machines "decrypt" our plaintext to "crypt-like" text. For anyone who would like to join the #freedom channel or acquire their encrypt/decrypt "on the fly" software, I have the following sug- gestions: 1. get on the Internet Chat system. 2. do a " /channel #freedom " command. that will get you into their channel. Immediately after getting on their channel, you will get a list of the nicknames of the users already on the channel. 3. IMMEDIATELY record on paper, the nicknames. - they may scroll off your screen quickly. 4. do a " /whois nick " on several of their nicks. This will get you their Internet email addresses. 5. Mail some of them requests for what you want. Since the channel name is "#freedom", I would suppose they are political & may want to share info. with you. If you are interested in their "on the fly" crypt/decrypt message software & you manage to get it - THEN BRING IT BACK TO CYPHERPUNKS! The stuff would make a good post on a Cypherpunk ftp site for freedom software. Note: it is possible that they may not be sophisticated with cryptography & might not want to give out their encrypt/decrypt algorithm. In which case, please try to get them in touch with one of the more experienced Cypherpunks. Cypherpunks should be able to demonstrate the uselessness of secret algorithms & in such a case give them stronger algorithms. Yours Truly, Gary Jeffers PUSH EM BACK! PUSH EM BACK!

you four will probably recall that I have just entered and left your encrypted channel on IRC. this message is crossposted to the cypherpunks mailing list; I, and I am sure other members of this list would be interested in the details of your encryption scheme, if any of you are willing to share. regards, josh

CU Crypto Session Sat
by Jeff Davis 17 Dec '03

17 Dec '03

-----BEGIN PGP SIGNED MESSAGE----- If old Sam gets his butt in gear, I should have a tape of the crypto session in Boulder yesterday to transcribe. Here's a brief report of the doings. Dr. Dorthy Denning of Georgetown University presented the escrowed encryption proposal. She was talking Boy Scouts and telephones, teaching kindergarten. Escrowed encryption was heinously soft peddled by Denning. The ramifications of escrowed encryption privacy violations by the intelligence communities was avoided during the initial presentation. She assured everyone that the FBI, with probable cause, would get a court order for the escrowed keys from NIST and DoJ. Rebutting was Phil Zimmerman, who was applauded when introduced as being under criminal investigation. Phil talked civil liberties, and some of the uses PGP was finding in countries not nearly as free from gov't intrusion as the United States. Phil brought up the point that intelligence agencies do not play by the same rules as the DoJ and FBI. Ken Klingenstein, CU director of comp. networking services, brought up the most interesting news to me. His perception of the DoD people he was in contact with was that they considered the escrowed encryption quagmire an NSA problem and were providing Klingenstein with helpful information. Denning had been nervous through out her presentation and response to the rebuttals of Phil and Ken. Again she avoided the issue of intelligence community intrusion, focusing on organized crime. I spoke to Denning briefly after the session. Eli Nixon, an investigator for the Zimmerman defense, and I proposed legalization for the drug problem. Denning sugested that organized crime would move into new territory in such an event. Slavery. (I found that rather anti-climactic after her dramatic measured pause for effect). Denning mentioned terrorists. I rebutted with satellite surviellance. I pointed out that we could read a poker hand via computer enhancement. This visibly shook her. Escrowed encryption is completely unnecessary, and she had no rebuttal for this. My information on satellite resolution came from a physicist who worked at JPL. I shook Dr. Denning's hand and wished her luck. She either reads everything I post, or was briefed beforehand. She was quite familiar with me. She couldn't believe I would discuss classified information on satellite resolution in casual conversation. The USAF hand in attendance was as smooth as sandpaper as well. As soon as I mentioned SDI, he shot over to evesdrop on the conversation I was having with Eli Nixon, et al. All and all, a fun time in Boulder. e -----BEGIN PGP SIGNATURE----- Version: 2.3a iQCVAgUBLbtGUl/ScHuGXWgVAQHlkAQAwl7sAz32H/zNxDUsPsy+LLEvGUCVScXY Zwr1oGpBqNYPVzDve46CvsissDpTH08MmQelfc+zwmdCjRP6sVzgNILhlsyLihTB Qfjh48sj40ESZnbJtj81k11SSaIBJJpDvlVsEWn4RDiP5aDgRnCKQ8hGxUZmGcCG q6dWYoH3DCc= =nGJZ -----END PGP SIGNATURE----- -- PGP PUBLIC KEY via finger!

Uh, Tim, I just tried out Prodigy. The only "net" access is via email. Saying that Prodigy is on the internet is analagous to saying that fidonet is. (I don't know if I'll say whether or not you've been the victim of false advertising, or whether Prodigy has done this). Phil

taming the wild pgp
by hh＠cicada.berkeley.edu 17 Dec '03

17 Dec '03

i'm having a problem with pgp. i want to use it in my remailer to decrypt incoming encrypted remail requests. the problem is this: someone could send in a keyfile instead of an encrypted text. according to the pgp manual, If you want to specify a particular key ring file name, but want to see all the keys in it, try this alternative approach: pgp keyfile With no command options specified, PGP lists all the keys in keyfile.pgp, and also attempts to add them to your key ring if they are not already on your key ring. this is bad because that's also the command used to decrypt a file. how can i make sure that the only thing pgp will attempt to do is decrypt a file, and it will never take keys from the input file and add them to any keyring? e
