Digital Signature Standard
Jump to user comments
cryptography, standard The NIST's standard for digitalsignatures (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's
security 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.
