摘　　要：盲签名是指签名者在签名时并不知道所签消息的内容,而且也无法确定自己是否曾经对某个消息签名.代理签名是指签名授权人委托某人代理其签名.结合盲签名和代理签名的特点,利用椭圆曲线上的双线性对,构造一个新的代理盲签名方案,并对其安全性进行了分析.分析表明,该方案具有可验证性、可区分性、盲性、不可伪造性、不可否认性等性质.代理盲签名在电子现金和电子投票等领域发挥着重要作用.In a blind signature scheme, the user can obtain the signature of a message in a way that the signer learns neither the message nor the resulting signature. And with proxy signature, an entity can entrust his signing authority to a proxy signer. In this paper, a new proxy blind signature scheme based on bilinear pairings is proposed by combining proxy signature with blind signature. This scheme has good properties such as verifiability, distinguish-ability, blindness, unforgeability, non-repudiation etc. Proxy blind signatures are used in applications such as e-cash and e-voting.
