Abstract: Because Shum-Wei anonymous proxy signature scheme has weakness of original signers forge attack and low implementation efficiency of the construction of discrete logarithm problem, this paper proposes a new anonymous proxy signature scheme based on ECC, and analyzes the essential security characters it has. It shows that the new scheme has the quality of high security and high efficiency of implementation.

Key words: elliptic curve, anonymous proxy signature, strong enforceability

摘要： Shum-Wei匿名代理签名方案存在原始人伪造攻击，且由于基于离散对数问题构造，实现效率不高。该文基于椭圆曲线公钥密码体制(ECC)构造了一个新的匿名代理签名方案，对新方案的各项基本性质进行具体分析。结果表明，新方案具有强不可伪造性，安全性高，实现速度快，具有较好的实际应用前景。
