| Abstract: | Yen-Cheng Chen et al. proposed an efficient nonce-based authentication scheme with key agreement in 2005. However, this authentication scheme has been found to be vulnerable to power analysis attack, off-line password guessing attack and internal attack. To solve this problem, an improved USB-Key-based authentication scheme is proposed, which can withstand the off-line password guessing attack and internal attack by means of improving the security policy and authentication information. The security analysis shows that the improved scheme still keeps the features of the non-storage data model authentication scheme and will not add the additional computation cost to the smart card. It will perform better in security and practical operations. |
