摘要
盲签名和代理签名在密码学中有各自的特殊用途。结合二者的优点,利用椭圆曲线上的Weil配对的双线性性质,在基于身份的签名基础上构造了一种改进基于身份的代理盲签名方案。该方案继承了前人的基于身份的代理盲签名方案的优点同时,运算效率进一步提高,代理人受到进一步的保护。最后对该方案的安全性进行了简要分析,从而证明了该方案是可行的。
Both proxy signatrue and blind signature have their own specific uses. Based on the bilinear property of Weil pairing defined on elliptic curve and ID-based signatue scheme, a modified ID-based proxy blind signatue scheme is presented, which inherits the adervantages of the present ID-based Proxy Blind Signatue Scheme, further reduces the computation and guarantes the profits of the proxy signer. Finally a simple security analysis on the scheme is given, and it is proved to be feasible.
