Internet users' platform move toward smart mobile devices like smartphones and tablet PCs, so the user authentication and access control for the mobile users are strongly required to support information securities. Mobile devices have weak points like low computing power, limited power, and restricted interfaces compared with the PC. So, these characteristics of mobile devices require light-weight and stable user authentication methods. This paper proposes user authentication LSAM (Lightweight & Stable Authentication Method) applicable to smart mobile devices (representatively Smartphone). LSAM gives a way to identify the users through random matrix displayed on smart mobile devices. Authentication Token used in LSAM is featured with variations on values of the matrix, so it is safe to replay attack and sniffing attack. LSAM does not need additional devices; it is just operated as the interface software on the mobile smartphone. We will show the evaluation criteria of the mainly used hacking techniques like the Challenger Variability, Replay Attack, Brute-force Attack, MITM (Man-In-The-Middle Attack) and measured the degree of defenses of our proposed authentication algorithm to these attacks. © 2011 Springer-Verlag.
