【摘要】 盲数字签名在电子选举协议、安全电子支付等领域应用广泛.针对已有离散对数盲数字签名方案的缺陷,基于求解离散对数问题的困难性,提出了一个改进型盲数字签名方案,可以同时满足盲数字签名的正确性、匿名性、不可伪造性和不可追踪性等特性要求.更多还原

【Abstract】 Blind signature plays abroad and important roles in cryptographic applications such as electronic voting system and electronic cash payment system.An improved blind signature scheme based on discrete logarithms is proposed.Compared with other blind signature schemes,our scheme can satisfy all requirements of a blind signature scheme.The security of the proposed scheme depends on the difficulty of solving the discrete logarithms problem.更多还原
