Congratulations to Marc Stevens, who described a method for fast collision attack on MD5!
Just now (! it is a collision !) I have finished the translation of my paper Vlastimil Klima: "Tunnels in Hash Functions: MD5 Collisions Within a Minute". It is based on a new method, tunneling. Using it on MD5 it gives a collision in 40 seconds on a 3 GHz Pentium 4. (Actually I used two times slower notebook with the time about 80 seconds.) I expect the publication on eprint also, but I will put in on my web together with the source code of the program in one or two hours. It is http://cryptography.hyperlink.cz/MD5_collisions.html Vlastimil Klima http://cryptography.hyperlink.cz/ ---------- Od: "Weger, B.M.M. de" <[EMAIL PROTECTED]> Komu: cryptography@metzdowd.com Predmet: MD5 collisions in one minute Datum: 17.3.2006 - 19:37:20 > Hi all, > > You might be interested in knowing that my MSc student > Marc Stevens has found a considerable speedup of MD5 > collision generation.
