基于身份签密的身份认证模型

身份认证方案是实现访问控制的重要工具.结合基于身份的签密思想和零知识协议,给出了一个身份认证方案模型,该模型可以实现通信双方的互认证,且可被任何一个基于身份的签密方案实例化.给出的实例化是以现存比较高效的一个基于身份的签密方案进行的.分析了实例化后方案的安全性,结果表明它可以避免重放攻击、伪造攻击、中间人攻击等常见攻击,且该方案可以容易地扩展为一个可认证的密钥协商方案.

Authentication scheme using identity-based signcryption

Authentication schemes are important tools finishing access control.By combining the idea of identity-based signcryption and zero-knowledge protocol,a model for authentication scheme is presented.The model can reach the two parties' mutual authentication in the communication and is instantiated by any identity-based signcryption scheme.The instantiation appeared is actualized by an existing effective identity-based signcryption.The result of analyzing the instantiated scheme shows that it is secure against ...
