一个基于ECC的双向认证协议

A Mutual Authentication Protocal based on Elliptic Curve Cryptography

1.引言 身份认证是网络安全技术的一个重要方面,身份认证机制限制非法用户访问网络资源,能够防止假冒、篡改、否认等攻击,确保用户的身份,是其他安全机制的基础.双向身份认证是指通信双方需要互相认证鉴别各自的身份[1,2].双向认证的典型方案是Needham-Schroeder协议.常见的认证协议还有分布认证安全服务(DASS)协议、ITU-T X.509认证协议等.

Identity authentication is important in network security. In this paper, a mutual authentication protocol based on Elliptic Curve Cryptography is designed and analysed. This protocol enables two entities to authenticate each other on computer network, defends any cheat, relay attack.
