Larry King show

Did anybody see the Larry King Live show last night (6/15)? He had Al Gore & others on, talking about the nations future information infrastructure. There were a few words about the Clipper. Gore said something like, "There are people out there who think that it's o.k. to do away with the FBI's ability to tap the communications of terrorists & drug lords." He went on to describe a future scenario where a terrorist group is able to detonate a nuclear device in an urban area because they can have secure communications. The show was pretty one-sided.

Actually, it isn't. The archive is not a web, in that it isn't the ideal hypertexted dream we all have. But it does have an extensive index, through wais. If you want to search for something in particular, you can try (with a URL browser, like lynx/mosaic) wais://pmipii.dist.maricopa.edu:210/crypt/Cypherpunks.src?remailer I forget the path, it'll show up when you try the http; the ? after the filename is followed by a wais search string, such as 'remailer'. You should be able to use a wais client to access this. I don't know how _old_ the archive is... ----------------------------------------------------------------------------- Rishab Aiyer Ghosh "Clean the air! clean the sky! wash the wind! rishab(a)dxm.ernet.in take stone from stone and wash them..."

I could not find any information on a time stamper site. BTW: Would a timestamp like this stand up in US court assuming that the lawyers were equal in their BS ratios?

The DES S-boxes were chosen to >make differential cryptanalysis difficult. Random S-boxes don't tend >to have this desirable property. Perhaps I should clarify: not DES with randomly-chosen fixed S-boxes; I'm well aware that those that DES uses are the best for differential cryptanalysis. However, as Bruce Schneier points out (p. 242), *variable* S-boxes make differential cryptanalysis impossilbe, as such an adaptive plaintext attack relies on knowledge of the composition of the S-boxes. If the boxes and their contents change with both keys used and plaintext--probably with the help of a strong RNG--then the only way such an attack could work would be by first figuring out what causes the changes in the S-boxes; in that case, the attack is probably already finished, by other means. Perhaps, even, the S-boxes could change with so many chunks of text--again, variable, of course. Most, if not all, of the actual S-box designs used would be much weaker than the original design of DES for differential cryptanalysis. However, each different plaintext (and key) would use different s-boxes, so that particular attack isn't possible. So, I guess part of my question should be, does this open up other attacks? Or, for that matter, am I completely wrong? And, like I said before, has this been done? >Use IDEA. Certainly, until there's something better.
