| 摘 要： | 提出一个具有失败-中止性质的代理签名机制。该机制的计算安全性基于离散对数问题，失败-中止性质的引入使签名伪造者拥有不受限的计算资源，可以破坏离散对数问题的难解性，成功伪造出有效签名，但诚实签名者能以极大的概率证明该签名是伪造的，以便原签名者及时采取应对措施。

| Abstract: | This paper proposes a proxy signature scheme with fail-stop property.Its computational security is based on discrete logarithm problem.Fail-stop property makes the signature forger with unbounded computational resources,so that he can indeed forge a valid signature,but honest signer can prove with overwhelming probability that the signature is a fake one.So that the original signer can take additional actions in time. |
