In 2004, Das, Saxena & Gulati introduced a new scheme called dynamic ID-based with the purpose of avoiding identity theft attack. Since then, many schemes have been proposed with the intention to improve security in different ways. Then, Sood et al. proposed a new scheme and claimed that it is more secure than Liou, Lin & Wang’s scheme. However, cryptanalysis study demonstrates that it is still vulnerable to guessing secret key attack, impersonation attack and steal information from a database attack, making it unsecure for electronic services. This paper proposes a new scheme that resolves the security flaws found in Sood et al.’s scheme and achieves all the security goals which a secure remote user authentication scheme should provide.
