this attack has only one advantage: 100% success rate. a rough estimate would be 500 fast (Gt200) cuda gpus working for 12 hours. (given that the copacobana does 2^36 a5/1 rounds per second). 12 hours is from the paper below, 2^36 is from some other paper which i could search the link for. 2^36 is about 500 times faster than a single GPU (2^27). in the same time you can decrypt hundreds of a5/1 ciphered streams with the tables.
one of the important attacks against A5/1 is this : http://www. > springerlink.com/index/p553233152534012.pdf > wanted to know what others think of implementing such attack on GPU?__ > _____________________________________________ A51 mailing list A51@ > lists.reflextor.com http://lists.lists.reflextor.com/cgi-bin/mailman/ > > listinfo/a51 ______________________________________________________ GRATIS für alle WEB.DE-Nutzer: Die maxdome Movie-FLAT!
