摘要
盲签密指盲签密者对其所签署的信息是不可见的,而且签密消息不可跟踪。有机集成自认证公钥密码系统和盲签密思想,提出了一个新的基于离散对数问题(DLP)的自认证盲签密方案。所提方案具有盲签密的各种安全特性;权威机构不知道用户私钥;不需要对用户的公钥进行单独认证;具有计算效率高、通信成本低、安全性强和算法简单等优点,适合于在电子商务和电子政务中应用。
Blind signcryption is that the blind signcrypter sees nothing about the signed message and can not trace the blind signcryption.By applying the concept of self-certified public key to blind signcryption,a new self-certified blind signcryption scheme based on Discrete Logarithm Problem(DLP)is presented.The new scheme keeps all kinds of security properties of blind signcryption;the system authority does not know the private key of the user;no certificate is required to verify the authenticity of public key;it has higher computational efficiency,lower communication overheads and better security,however,the algorithm is simple,so it is more suitable for applications in E-commerce and E-government.
