文中提出了一个基于环Zn上的圆锥曲线的代理盲签名,并对该方案做了分析。该方案的安全性是基于大整数的因数分解困难性和有限群上计算离散对数问题的困难性,由于阶的运算以及点的运算在Cn(a,b)上比较容易,且通过引进标准二进制计算群元素的整数倍的算法,使该方案具有运算速度快,易于实现等优点。 In this paper, we propose a proxy blind signature based on the conic of ring Zn, and analyze the scheme. The security of this scheme is based on the difficulty of factorization of large integers and the difficulty of computing discrete logarithm problems on finite groups. It is easier to compute Cn (a, b) Binary calculation group integer multiples of the algorithm, the program has the computing speed, easy to implement and so on.
