DES challenge status?
-----BEGIN PGP SIGNED MESSAGE----- What exactly is the status of RSA's DES contest? I understand that at least two of the smaller contests have already been cracked, but I haven't seen much beyond theoretical discussion on the list on the topic of the DES contest. What work has been started on this contest? I am aware of Peter Trei's excellent deskr software for win32, but at the moment it chokes on RSA's real contest data as distributed. Has anybody yet worked on porting a version to x86 Linux, with nice, fast, inline assembly? How about a keyrange-server? This contest is so huge that any procedural innovations will probably be much more helpful than getting an early start. Has anybody started work on this yet, or is everyone else waiting for someone else to do it? - -- Ben Byer root@bushing.plastic.crosslink.net I am not a bushing -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQB1AwUBMvAb/LD5/Q37XXHFAQFxtQL/b7PeoWoO8gW0R35eOcA7yDmNOzg5IbIX xbrWkX0D7Tnj+8BxeQkRs2lOhhB6D6V/oh7RO6zMUwbNVaPDng0vjZXEmHAUVPnL XwSfekx47rgc43mVuXJoyval1zZuKDjE =h76F -----END PGP SIGNATURE-----

Two? The only publicized solution so far is the RC5/32/12/5 solution from Ian Goldberg at Berkeley (and independently from Germano Caronni at ETH Zürich). Are you saying that you know that the 48 bit RC5 contest is solved already, or are you just counting Ian's and Germano's solutions separately? -- Anil Das

Ooops! Mea culpa. That's what I meant. - -- Ben Byer root@bushing.plastic.crosslink.net I am not a bushing -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQB1AwUBMvFohbD5/Q37XXHFAQFBIQL+IiN8gFqyjvxhvJ6C0hN4KecTbD82Vwmp nD0w79LxR0fX+E4unJf/QvEdVh8FkrMqwO39MtYB3dIXqepljOlKDjs7DveRv+Fp eGtCSl7OayCdgtKUe32ELr+px0Y8Rsqj =UZps -----END PGP SIGNATURE-----
