An Effcient Blind Signature Scheme Based on the Elliptic Curve Discrete Logarithm Problem

Elliptic curve cryptosystems (ecc) have recently received significant attention by researchers due to their high performance such as low computational cost and small key size. in this paper a novel untraceable blind signature scheme is presented. since the security of proposed method is based on difficulty of solving discrete logarithm over an elliptic curve, performance of the proposed scheme is quite commendable in comparison with the previous work in terms of security and time complexity.
