摘要: 基于智能卡的身份鉴别是一种双因子鉴别,被广泛应用于鉴别远程用户的身份。2006年,Liao等人提出了一种基于智能卡的身份鉴别方案。在目前身份鉴别研究的基础上,分析指出了Liao等人方案存在的安全漏洞,并对方案作了改进,改进后的方案不仅保持了Liao等人方案的优点,而且极大地增强了系统的高效性、安全性和实用性。

Abstract: Smart card-based authentication is a two-factor authentication mechanism,which is widely used for remote user authentication.In 2006,Liao et al proposed a smart card-based authentication.Based on the modern studies,the safety flaws of Liao et al’s program are pointed out.And then an improved authentication scheme based on smart card is proposed.The improved program not only maintains the advantages of the Liao et al’s program,but also performs better among efficiency,security and flexibility.
