Designated-verifier monotone signature scheme with multi-security level
Yongqiang Li · Journal of Zhengzhou University of Light Industry · 2007
By computing the random power of the designated verifier's public key in the finite field and signing the result and the message by using the monotone signature scheme,a designated-verifier monotone signature scheme is proposed,where the signature keeps the properties of the monotone signature and has many security grades,and only the designated verifier can verify the signature. Then it is more secure than the ordinary designated-verifier signature scheme.
