随着信息技术和网络技术的快速发展,互联网实名制已经成为网络监督和管理的重要趋势,而用户身份认证又是实名制管理体系中的关键技术。首先介绍了基于智能卡的身份认证协议,讨论了该协议存在的不足,并在此基础上,提出了一种基于ECC双因子的身份认证协议,通过椭圆曲线离散对数难题和时间戳因素确保协议的安全性,解决了丢失智能卡攻击的问题,并且保持了协议的高效性。
With the rapid development of information technology and network technology, Internet real name system has become an important trend of network supervision and management, and user authentication is a key technology in real name management system. First of all, based on smart card authentication protocol, discussed the shortcomings of the agreement, and on this basis, proposed a two-factor authentication based on ECC protocol, elliptic curve discrete logarithm problem and timestamp factors to ensure that the agreement Security, to solve the problem of losing smart card attacks, and to maintain the efficiency of the agreement.
