Abstract

With the rapid growth of Internet users and wireless applications, interests on home networks have been enormously increased in recent years. For digital home networks, robust security services including remote user authentication have become essential requirements. In order to reduce implementation complexity and achieve computation efficiency, design issues for efficient and secure password based remote user authentication scheme have been extensively investigated b research community in these decades. Recently, Vaidya et al. proposes a robust one time password authentication scheme using smart card for home network environment. The authors claimed that their scheme delivers important security features and system functionalities, such as mutual authentication, no verification table, no time synchronization, resistance against password guessing attacks, smart card loss attacks, forward secrecy with lost smart card and forged user attacks, as well as computation efficiency. However, we first demonstrate two vulnerabilities on the scheme. Then, we propose an improved scheme to eliminate all identified security flaws in the scheme.
