Title:
Cryptanalysis of Sood et al.’s Authentication Scheme using Smart Cards

Authors: Rafael Martínez-Peláez, Francisco Rico-Novella

Abstract:

In 2010, Sood-Sarje-Singh proposed a dynamic ID-based remote user authentication scheme and claimed that their scheme is more secure than Das et al.’s scheme and Liao et al.’s scheme. However, we show that Sood et al.’s scheme is still vulnerable to malicious user attack, man-in-the-middle attack, stolen smart card attack, off-line ID guessing attack, impersonation attack, and server spoofing attack, making the scheme unfeasible for practical implementation.
