To prevent the forged login attacks, Liu et al. recently proposed a new mutual authentication scheme using smart cards. However, we demonstrate that the attacker without any secret information can successfully not only impersonate any user to cheat the server but also impersonate the server to cheat any user. That is, Liu et al.’s scheme fails to defend the forged login attack as the previous version.
