Proposal - The 'Peterson.mil' Virus List
by deltorto＠aol.com 22 Feb '93

22 Feb '93

Yo, Punks I propose that we establish another list dedicated to the study of viruses and name it after Keith Peterson. After all, why shouldn't he get some credit for awakening a sleeping giant? I want to know more about viruses so I can protect myself from government-created viruses and so I can learn about the various mechanisms involved. In addition, the study of self-promulagting code has very positive implications for the study of "smart email." For those of you who haven't been following the exploits of General Magic and their Telescript protocol, there will soon be mail which "delivers itself" to the right location. I'm sure our members at General Magic can illuminate this subject further. The implications of this technology reach into the world of encryption and viruses and certainly further into the realm of privacy discussions. Wot say, all? d2t

Recently there was a thread on a public-key program that would involve a central, government-backed-or-authorized agency to issue key pairs and serve as a repository. Could someone please post some details on this -- I seem to have gotten it into my head that this is how PEM works, and I don't know whether I'm right or just medicated. :-) Loyd *************************************************************************** * loydb(a)fnordbox.UUCP Call the Fnordbox BBS * Loyd Blankenship * * GEnie: SJGAMES 2 v32bis lines, 24 hrs * PO Box 18957 * * Compu$erve: [73407,515] 512/444-2323 * Austin, TX 78760 * * cs.utexas.edu!dogface!fnordbox!loydb * 512/447-7866 * ***************************************************************************

Brunner's novel explicitly mentions the notion of viruses as well as tapeworms. Remember the "phages"? A phage is a virus. Perry

Government encryption

Loyd Blankenship asks whether PEM involves having a government agency create key pairs. I think this may be confusing two different issues. PEM does not involve having anyone else create key pairs for you. You create your own keys and keep the private key secret just as in any other public key system. However, PEM requires you to get a "certificate" from an agency in order to use the system. The certificate-issuing agency is typically expected to be your employer or your university, from my reading of the RFC's. Large institutions like these would issue certificates, which are basically similar to PGP's key signatures, which certify that you are who you say you are. The large institutions themselves would have their own public keys signed by an agency higher in some key-signing hierarchy. Last I checked, the top of the hierarchy was the company RSADSI; they would certify the companies and the companies would certify the employees. I think this part may have changed a little in the last few drafts of the new RFC. So, there's not really any government involvement. There is a centralized hierarchy for key signatures, but key generation is still an individual activity. Oh, yes, there may also be a charge for getting your key signed; this charge might be borne by the company/university in some cases. There is also a provision to get a certificate outside this system; these "persona" certificates wouldn't really vouch for anything but they would let you use PEM. I'm not sure what they will cost. The other idea which Loyd might have been mixing up with this was Dorothy Denning's proposal several months ago that all users of public key systems be required to register their secret keys with some quasi-governmental agency. (Originally she proposed the Justice Department, then later suggested an independent group.) This way if the government wanted to spy on your communications, it would have to get a court order (as it does now, in theory, for wiretaps), and take this court order to the key-holding agency to get them to reveal your secret keys. Then it could read your messages. This proposal was subjected to a very strong attack led largely by our own Tim May. It soon became known as the "lead balloon" for its lack of support and has not been heard of recently. I don't think anyone would be terribly surprised if some variant were to resurface, though.

Could someone please post some details on this -- >I seem to have gotten it into my head that this is how PEM works, and I >don't know whether I'm right or just medicated. :-) > >Loyd The proposal was slightly different and has not been officially proposed as any kind of law. Here are some more details: * Dorothy Denning, noted cypto and security expert, floated a trial balloon at the Computer Security Conference last fall. (I summarized it and posted it to sci.crypt, where more than 1000 messages related to this thread, "A Trial Balloon to Ban Encryption?," eventually appeared.) * Under her proposal, a user of P-K methods would take his _private_ key and encrypt it to the _public_ key of an agency like the Justice Department (which I'll use from now on to represent the government side). The encrypted key would then be placed in a repository with another agency, perhaps a private agency like the CPSR or even the EFF. The key storage agency obviously could not read the messages (as they would be encryped to the Justice Deparment's key). * A properly-obtained warrant could then be presented to the key repository, obtaining the specific key. The Justice Department could then decrypt with its private key and thus have the private key of the user. * Ostensibly, this prevents the Justice Department from simply snooping through whatever messages it wishes to read. * There are some obvious practical and constitutional issues: - What happened to constitutional rights to privacy? Analogously, must one escrow personal diaries? Install tape recorders in all private places and escrow copies of all tapes? (Lots of comparisons to free speech, to gun control, etc.) - What happens when people register the "wrong" key? Is this even detectable? - If "noise" is sent, will the Justice Department demand the "key" be presented? How? And what penalties for noncompliance? - Many applications demand dynamic generation of keys---many public keys, many session keys, etc. How will these be registered? What fees? - It seems likely that a key registration scheme will also place limits on many of the things we hold dear on this list--digital money, anonymous systems, remailers, and all the other wonders of crypto anarchy. There's a lot more. And there was a lot of debate in sci.crypt about this. Fortunately, I don't see any further moves to make this a law. But it may come in a few years. -Tim May -- Timothy C.
