An identity based cryptosystem is a novel type of public cryptographic scheme in which the public keys of the users are their identities or strings derived from their identities. ...
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. Proxy signature schemes allow an original signer to delegate his signing rights to a proxy signer. Most proxy signature schemes have succeeded for proxy delegations and t...
Abstract. We firstly proposed a new notion of short identity-based signature scheme. We argue that the identity-based environment is essential in some scenarios. The notion of sho...
This paper proposes a new ID-based proxy signature scheme based on the bilinear pairings. The number of paring operation involved in the verification procedure of our scheme is onl...
