Tach! Aktueller Stand der Hash-kollisionsdingsbums:
<http://www.freedom-to-tinker.com/archives/000664.html> "One of the Chinese authors (Wang, Feng, Lai, and Yu) reported a family of collisions in MD5 (fixing the previous bug in their analysis), and also reported that their method can efficiently (2^40 hash steps) find a collision in SHA-0. This speaker received a standing ovation, from at least part of the audience, at the end of her talk." "Eli Biham announced new results in cryptanalyzing SHA-1, including a collision in a reduced-round version of SHA-1. The full SHA-1 algorithm does 80 rounds of scrambling. At present, Biham and Chen can break versions of SHA-1 that use up to about 40 rounds, and they seem confident that their attacks can be extended to more rounds. This is a significant advance, but it's well short of the dramatic full break that was rumored." Fazit: MD-5 ist gepl�ttet (Hach was freue ich mich schon auf die Updaterei bei diversen *nix-kisten die das f�r Passw�rter verwenden...), SHA-1 lebt noch. Bernd Every cloud has a silver lining (except for the mushroom shaped ones, which have a lining of Iridium & Strontium 90) _______________________________________________ Coffeehouse Mailingliste, Postings senden an: [EMAIL PROTECTED] An-/Abmeldung und Suchfunktion unter: http://www.glengamoi.com/mailman/listinfo/coffeehouse
