standard> The NIsT' sstandard for {digital signatures} (authenticating both a message and the signer) that was first announced in 1991. It is based on an algorithm using discrete logarithms, which is a variant of the Elgamal algorithm with schnorr' s improvements. Dss' ssecurity is currently considered very strong - comparable to RsA. It is estimated that Dss' s 1024-bit keys would take 1.4E16 MIPs-years to crack. (1995-11-16)
