为了满足电子现金、电子招投标等特殊系统的安全性需求,在研究分析椭圆曲线密码、自认证公钥、位委托协议和Nyberg-Rueppel签名方案的基础上,设计了一种系统中心控制和多方参与的安全盲签名方案,并对该方案的正确性、安全性进行了必要分析和证明。
In order to meet the security requirements of special systems such as e-cash and e-bidding, this paper designs a system-centric control and multi-party system based on the research on elliptic curve cryptography, self-certifying public key, bit entrustment protocol and Nyberg-Rueppel signature scheme. Participate in the safe blind signature scheme, and analyze and prove the correctness and safety of the scheme.
