Re: Cryptanalysis of S-1
OK lets turn this on its head, I think we now have a good idea of how to build a
cipher in clean room conditions such that nobody is aware of the full details of
Team 1: Develop an encryption network, implement as hardware
Team 2: Test various combinations of keyspace.features without being exposed to
inner workings of the cipher.
Develop your Clipper chip this way and nobody can reveal the source. Fun huh?
I think we are about to see a cascade of Skipjack hoaxes regardless of the
provenance of the original. Now people have the idea the clueless newbies will
I'm suprised nobody has tried before, I thought of constructing a Skipjack hoax
based on DES but with larger S boxes. S1 could be made to run very fast, a
straight through pipeline would be very nice in hardware. Anyone care to suggest
how a secure cipher might be based on it (ie appart form the clearly bogus key
I think a score sheet is in order, marks out of 5 for what? Distribution,
technical ingenuity, credibility, annoying Dorothy, hardware suitability,
software suitability... ?
Perhaps the NSA might volunteer to serve the page with the cumulative judgments.
