About a month ago annual Eurocrypt conference took place in Cologne, Germany. This is rather academic event (as most if not all events held by IACR) so it is not always easy to read its proceedings filled with formulas and theorems. Nonetheless there are usually couple of very interesting works presented at each such event. Let me tell you a little bit about this year’s highlights.

Unfortunately, almost no further/technical details — more cores is definitely good, but we’d like to see whether AMD is able to implement SSE2 effectively. Right now, SSE2 instructions are executed much slower on AMD processors than on Intel ones, while they’re really important for SHA-1 (the most password checking routines are based on). Or may be SSE5 will give provide additional benefits for password cracking?
