摘要： 针对现有签名方案不能同时保护代理签名者和消息拥有者的利益问题，提出一个椭圆曲线上的盲代理盲签名方案，利用椭圆曲线公钥密码体制和零知识证明使该方案计算量小、安全性高、实现效率和实用性较高。安全性分析证明，该方案同时具备盲代理签名和代理盲签名的各项安全性质以及强不可伪造性。

Abstract: Aiming at the problem that current schemes can not protect the benefits of proxy signer and message owner at the same time, this paper presents a blind proxy blind signature scheme on elliptic curve. By using Elliptic Curve Cryptography(ECC) and zero-knowledge proof, it has small amount of computing, high security and high implementation efficiency. Security analysis proves that the scheme satisfies the security properties of blind proxy signature scheme and proxy blind signature scheme, and it has strong enforceability.

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