We formalize a generic method of constructing efficient group signatures, specifically, we define new notions of unlinkable randomizable signature, indirectly signable signature ...

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 ...

Abstract. We introduce a short signature scheme based on the Computational Diffie-Hellman assumption on certain elliptic and hyper-elliptic curves. The signature length is half the...
