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.
Key words:
digital signature,
proxy signature,
fail-stop signature
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。
