Efficient Constrution of Strong Designated Verifier Signature
Yang Shu-si · Science Technology and Engineering · 2007
A common characteristic of some private designated verifier signature schemes is point out.Underlying these is a overlooked framework:in some sense,they are all message authentication code schemes(MAC)with the private key generated through the famous Diffie-Hellman protocol.With this framework,be can modularly construct private designated verifier signature schemes which are much more efficient than the previous ones.
