摘要
为了满足电子招投标系统的安全需求和提高它的运行效率,在分析椭圆曲线公钥密码、自认证公钥、Nyberg-Rueppel签名方案和位委托协议的基础上,设计了一种安全有效的盲签名方案,并对该方案的正确性、有效性和安全性进行了必要分析和证明.
To meet the security requirement of e-bidding systems and improve its running efficiency, a secure and efficient blind signature Scheme is designed based on the analysis of elliptic curve public key cryptosystem, self-certiffed public keys, Nyberg-Rueppel signature scheme and bit commitment protocol. Its validity and effectiveness and security are verified.
