基于ECC的限制性盲签名电子现金支付的研究

摘要

椭圆曲线密码体制(ECC)构建的电子现金系统具有更短的密钥长度与更高的计算效率,提出了基于ECC的限制性部分盲签名及离线电子现金方案,实现系统参数、取款协议、支付协议和存储协议的研究.%Taking advantages of the excellent performance of ECC and this paper proposes an elliptic curve restrictive partially blind signature and off-line e-cash scheme. ECC-based restrictive partially blind signatures and off-line electronic cash payment are presented. It achieves the system parameters, ATM protocol, payment protocol and storage protocol.
