一个前向安全盲签名方案的分析与改进
Cryptanalysis and Improvement of a Forward-Secure Blind Signature Scheme
摘要
Abstract
Cryptanalysis of the forward-secure blind signature scheme proposed by He Junjie et al .showed that the scheme does not satisfy forward security .An improved forward-secure blind signature scheme was proposed .Analysis results showed that the improved scheme has forward security under the assumption which make solving the square root and 2 l-th root of a quadratic residue hard , and its unforgeability dependends on the hardness of discrete logarithm problems and the problems of computing 2 l-th root of a quadratic residue .关键词
