改进方案仍然容易受到并行会话攻击

The Modified Scheme is still vulnerable to the parallel Session Attack

Manoj Kumar

摘要:

2002年,Chien Jan Tseng提出了一种使用灵巧卡的高效远程用户认证方案。–– 2004年,W. C. Ku和S. M. Chen提出了一种利用灵巧卡的有效的远程用户认证方案,以解决Chien等人的安全问题。8217; s方案。最近,Hsu和Yoon等人指出了Ku和Chen方案的安全性弱点,Yoon等人对Ku和Chen方案的口令修改阶段进行了改进,并提出了一种新的基于灵巧卡的高效远程用户认证方案。’’分析了Yoon等人的改进方案仍然容易受到并行会话攻击。

英文摘要:

In 2002, Chien–Jan–Tseng introduced an efficient remote user authentication scheme using smart cards. Further, in 2004, W. C. Ku and S. M. Chen proposed an efficient remote user authentication scheme using smart cards to solve the security problems of Chien et al.’s scheme. Recently, Hsu and Yoon et al. pointed out the security weakness of the Ku and Chen’s scheme Furthermore, Yoon et al. modified the password change phase of Ku and Chen’s scheme and they also proposed a new efficient remote user authentication scheme using smart cards. This paper analyzes that the modified scheme of Yoon et al. still vulnerable to parallel session attack.
