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。 Blind and proxy signatures have their own specific uses in cryptography. Combining the advantages of the two, an identity-based proxy blind signature scheme is constructed on the basis of identity-based signature by using the bilinear property of Weil pairing on the elliptic curve. The scheme inherits the advantages of the previous identity-based proxy blind signature scheme. At the same time, the computational efficiency is further improved and the agents are further protected. Finally, the security of the program is briefly analyzed, which proves that the program is feasible.
