摘要: 提出一个可证安全的无证书代理签名方案。该方案满足代理签名所有的安全性质。在随机预言模型下,给出了它正式的安全证明。它的安全性基于计算Diffie-Hellman问题的困难性。同时,在该代理签名方案的基础上,给出了无证书代理盲签名方案。

Abstract: In this paper,a provably secure certificateless proxy signature scheme is presented.It satisfies all the properties required for a proxy signature.This paper provides complete security proofs for the proxy signature scheme.The scheme is proved secure in the random oracle model with the assumption that the computational Diffie-Hellman problem is infeasible.At the same time,this paper puts forward a certificateless proxy blind signature scheme,which is based on the proxy signature scheme.
