Cryptanalysis and Improvement of Yan et al.'s Biometric-based authentication scheme for Telecare Medicine Information Systems | Dheerendra Mishra

19 Sep 2013 | Abstract: | Remote user authentication is desirable for a Telecare medicine information
system (TMIS) to verify the correctness of remote users and server over the
insecure channel. In 2013, Tan presented a biometrics based remote user
authentication scheme and claimed that his scheme is secure. Recently, Yen et
al. Analyzed Tan’s scheme and identify serious security flaws, namely,
denial-of-service attack. In this article, we analyze Yan et al.’s scheme and
show that their scheme is vulnerable to off-line password guessing attack.
Moreover, we identify the inefficiency of Yan et al.’s scheme login and
password change phase. Further, the article presents an improvement of Yan et
al.’s scheme for TMIS to eliminate all the drawbacks of Yan et al.’s scheme. | Source: | arXiv, 1309.4944 | Services: | Forum | Review | PDF | Favorites |
