Several pieces on the export of encryption regs, the crypto czar, Motorola's crypto modem, PGP's buy of PrivNet, and Keytronic's finger-ID keyboard. Professor Denning opines that the HP doodad will include GAK. ----- http://jya.com/doodad.txt DOO_dad ---------- The NYT has a long report today on a pedophile computer racket run from a prison. With details on how investigators were able to break through hard drive security and use DejaNews to track a suspect. A prison computer business was used to cloak the kiddy pixels. Red flags the Internet's lurid prospects compared to the virtues of do-me-dads like the Times. see: www.nytimes.com

RE: NT insecurity
by Kenneth L. Hamer 17 Dec '03

Really? Could you provide a reference for this assertion? What is the name of the "password file"? Where is it located on the disk? I'd be very interested to try this out on one of my test systems, especially if it is true. But my experiences with corrupted registry hives leads me to believe you are incorrect. NT usually does nothing so nice when it's registry is corrupted. That's why we keep "emergency repair disks" around 8-). - Ken >---------- >From: Adamsc@io-online.com[SMTP:Adamsc@io-online.com] >Sent: Monday, November 11, 1996 9:36 PM >To: cypherpunks >Subject: BoS: NT insecurity > >Given the recent comments about insecure machines, I thought it was >interesting to note that you can clear *every* password on an NT box by >using >a diskeditor to corrupt the password file (Boot off of a floppy and use >NTFSDOS if you have to).

TIS + HP
by John Young 17 Dec '03

17 Dec '03

A blurb in the Wash Post today says that the HP roll-out this morning will include TIS's "trusted third party" product. "One essential ingredient in the equation: technology developed by TIS. TIS is so far the only company that has received permission to export encryption technology overseas that exceeds the government's existing threshold." Guess we'll know shortly who else in the System is to be Trusted with Information -- other than Thirds, Fourths and other Dots and Steves.

Re: Members of Parliament Problem

So how can he confirm that the message is actually from > a member of the group when he doesn't see it? I should have elaborated a little on this. My idea was that trent should be able to decrypt the message and verify it was meaninful (at least probably so) by some form of frequency analysis, as he would be a computer program this would not be a significant time loss in a system with few users (such as parliament as suggested with the initial problem) if the resulting message didn`t have approximate frequency distributions of letters you would expect in natural langauge or source code or whatever the message would not be published as it is probably an invalid key being used thus decrypting to garbage. A better way to do all this would probably just be to have Bob sign the message then Trent strip the signature before signing it himself but I just dashed this off as a quick response without really thinking it through. A nicer protocol would be one where the key distribution is easier initially (isn`t this always the case ;-)) or even a protocol which isn`t arbitrated, like your reply said Chaum mentions protocols for this.

With TIS bending over for the big GAK Monster in so many ways, it brings up a question... (A probibly off-topic one...) Does anyone know of intentional GAK-like holes put in their Firewall Toolkit? They distribute it for free and distribute source, but with their record i have little trust in the matter...

> If you do not send it to me by e-mail, I will never see it. > Why are you so paranoid that someone is reading your e-mail? > I never do anything criminal, so I could give a shit less if > everybody reads all of my fucking mail. I was trying hard not to get into this thread as it is basically just one long flamewar that is getting out of control but I have to comment here: There need be no reason for paranoia. I don`t call it paranoia, I call it constant vigilance, to demonize it is a statist position and tries to ostricise those who protect their privacy. Whether you do anything criminal or not is not the point. Indeed I would say that 90-95% of encryption usage is for perfectly legal purposes, and only about 0.1% of encrypted material is concerned with unethical acts rather than illegal acts. The point is you should retain the right to protect your privacy. Sure, it`s not illegal to put forward anarchist arguments in mail today, but do you really want your company boss knowing about it? I personally don`t work - I`m a student so it doesn`t matter to me, but whether it is right that your employement and political views should affect each other they do, so you should be able to protect yourself with technology...

Playing card cryptosystems

> Also I did hear tell that Bruce Schneier was working on a crypto > algorithm which was designed to work with playing cards, for a book > which Neal Stephenson is writing. Presumably painful to use, but > maybe good plausible deniability, all that you need is a pack of > cards. Not even that in fact, there are methods, and I can confirm they work because I can do it myself, that allow one to memorize the order of a pack of playing cards, some people can even do it with up to 8 packs, although this requires a more complicated method. So while encryption requires one to have the cards ready (about 8 good riffle shuffles will restore a high degree of randomness to a deck) you can keep the pad for short messages in your head. But one can do the same with one time pads that use other plaintexts as the pad.
