That would be a breakage of RSA, not D-H or DSA. Hello, While I am not in par with the advances in solving the DLOG problem, the ECRYPT 2010 report on key sizes mentions in section 6.1: "According to the state of the art the difficulty of solving DLOG in prime order fields of size 2^n is, up to constants, asymptotically equivalent to that of breaking n-bit RSA". Given that all reports on key sizes agree on that (ECRYPT is not related to NIST in any way), I wouldn't ignore these recommendations. regards, Nikos
