We first analyze the security of a short signature scheme without random oracles called ZCSM scheme and point out that it cannot support unforgeable under the chosen message and ...

Batch verification can provide large computational savings when multiple signatures are verified together. Recently, some batch verifying signature schemes have been proposed from...
In 2004, Libert and Quisquater proposed an identity based undeniable signature scheme using pairings over elliptic curves. In this article, we show that the scheme is not secure. ...

In this paper, we present the first certificateless undeniable signature scheme. The scheme does not suffer from the key escrow problem, which is inherent in identity based crypto...
Restrictive blind signatures allow a recipient to receive a blind signature on a message not known to the signer but the choice of message is restricted and must conform to certain...
