There are two new papers on the Twofish website: - The second Twofish Technical Report, where we give the results of our empirical verification of some Twofish key uniqueness properties. This result gives us further confidence that there are no related or weak keys. - An initial cryptanalysis of Magenta, one of the other AES submissions. This short paper was written at the first AES workshop, hours after the Magenta algorithm was first released. Certainly there are improvements to this attack, and beginning cryptography students would do well to work on this algorithm. Both of these papers are on the Twofish website: http://www.counterpane.com/twofish.html Also, the Twofish Pentium assembly code had a small bug in it; revised code is available on the website. We are interested in other implementations of Twofish. If anyone has ported the algorithm to Visual Basic, Perl, Motorola assembly, or any other smart card processor, and is willing to make their code public, we'd be happy to hear from them.
