基于椭圆曲线的可认证三方密钥协商

Authenticated Tripartite Key Agreement Based on Elliptic Curve

随着网络应用的发展,密钥建立技术成为安全数据通信的基础。密钥建立包括密钥传送和密钥协商。文中基于椭圆曲线公钥密码体制和Diffie-Hellman问题构造了两个可认证三方会话密钥协商协议,具有较强的安全性和较高的效率,可满足三方通信或需要特殊服务的两方通信的需要。

With the development of network application,key establishment has become the foundation of secure data communication. Key establishment includes key distribution and key agreement. In this article, two tripartite key agreement protocols are devised based on elliptic curve public key cryptography and Diffie-Hellman problem. The protocols are secure and efficient, which can meet the demand of three party communication and can be used to provide a range of services for two parties' communication.
