FIPS PUB 186-2, DIGITAL SIGNATURE STANDARD (DSS) (JAN 2000)

FIPS PUB 186-2. This standard specifies a suite of algorithms which can be used to generate a digital signature. Digital signatures are used to detect unauthorized modifications to data and to authenticate the identity of the signatory. In addition, the recipient of signed data can use a digital signature in proving to a third party that the signature was in fact generated by the signatory. This is known as nonrepudiation since the signatory cannot, at a later time, repudiate the signature.
