Digital Signature Standard

   <cryptography, standard> The {NIST}'s {standard} 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'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.
