Cryptographic signature verification using two private keys.

摘要

A digital signature verification protocol utilises a pair of signature components incorporating a pair of private keys one of which is a long term key and the other of which is a short term key. The long term key is applied to one of the signature components to reveal the short term key. The short term key is then used to compute a value of a signature component contained in the signature. If the computed value and received values agree then authenticity is verified. It can be used with smart cards.
