  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.
