摘要: 2005年,Lu-Cao指出Hwang-Li远程用户认证方案易遭受身份假冒攻击,并提出了使用智能卡的远程用户认证方案来修补这种安全缺陷。论文分析指出Lu-Cao远程用户认证方案仍存在某些安全缺陷,并介绍了一种改进的远程用户认证方案。

Abstract: In 2005,Lu-Cao proposed an improvement on Hwang-Li’s remote user authentication scheme using a smart card that could withstand an impersonation attack,but also it required fewer computational costs.However,the current paper demonstrates that Lu-Cao’s scheme also has some security drawbacks,and presents an improved authentication scheme in order to solve such problems.
