Abstract
This paper finds the same framework underlying some designated verifier signature schemes: each of them can be seen as a message authentication code scheme (MAC) where the private key is generated by the Diffie-Hellman key agreement protocol. So all these schemes could have been very simply constructed. Utilizing this framework, we can modularly construct private designated verifier signature schemes with better efficiency.
