摘　　要：在代理签名中,原始签名人能将其数字签名的权力委托给代理签名人;而在盲签名方案中,被签消息的内容对签名者是不可见的,签名被接受者得到后,签名者不能追踪签名。文章结合二者的优点,利用基于椭圆曲线上的Weil配对的双线性映射,在基于身份的数字签名的基础上,构造了一个基于ID的代理盲签名方案,并对其安全性作了简要分析。Proxy signatnre and blind signature are useful tools in cryptography. They both have wide applications in real life. In a proxy signature, an original signer can delegate his signing power to a proxy signer who signs a message on behalf of the original signer. A blind signature has a salient feature that the signer can not make a linkage between the blind signature and the identity of the requester. Based on bilinear paring and an ID-based signature scheme, an ID-based proxy blind signature scheme is presented, which satisfies the security properties of both proxy signature schemes and blind signature schemes. A simple security analysis of the newly proposed scheme is also given.
