一种改进的基于ECC双因子身份认证协议

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。

An Improved Double-Gene Identity Authentication Protocol based on ECC

With the rapid development of information technology and network technology, the Internet real- name system now becomes an important trend of network supervision and management, while the user iden- tity authentication is the key to the real-name system. The identity authentication protocol based on smart- card is firstly described, and then the flaw of this protocol is discussed. With this, a double-gene identity authentication protocol based on ECC is proposed. And by using the elliptic curve discrete logarithm prob- lem and timestamp factor, the security of this protocol is ensured, the problem of smart-loss attack solved, and the high efficiency of the orotoeol maintained.
