一种高效的基于身份的代理盲签名方案

在代理签名中，原始签名人能将数字签名的权力委托给代理签名人；而在盲签名方案中，签名者不能看到被签消息的内容。签名被接受者得到后，签名者不能追踪签名，结合代理签名与盲签名的优点，利用基于椭圆曲线上的Weil配对（WeilPair—ing）的双线性映射，构造了一个高效的基于身份的代理盲签名方案．分析表明，该方案不仅满足代理盲签名所要求的所有性质，而且其效率也优于已有同类方案．

An Efficient ID-based Proxy Blind Signature Scheme

With proxy signature,an original signer can delegate his signing authority to a proxy signer who signs a message on behalf of the original signer.In blind signature scheme,a signing messages are unknown to the signer,which makes the blind signature and the identity of the requester cannot be traced.Based on bilinear projection of Weil Pairing,an efficient ID-based proxy blind signature scheme is presented by combining proxy signature with blind signature scheme.The analysis shows that the proposed scheme can satisfy all the required properties of a proxy blind signature.Furthermore,its efficiency is also better than that of the exiting schemes.
