FIPS 186 -
(DSS), Digital Signature Standard
A Digital Signature (not to be confused with a
digital certificate) is an electronic signature that can be used to
authenticate the identity of the sender of a message or the signer of a
document, and possibly to ensure that the original content of the message or
document that has been sent is unchanged. Digital signatures are easily
transportable, cannot be imitated by someone else, and can be automatically
time-stamped. The ability to ensure that the original signed message arrived
means that the sender cannot easily repudiate it later.
