• Recently, Hwang and Li proposed a smartcard-based remote user authentication scheme. Later, Chan and Cheng showed that Hwang arid Li's scheme is insecure against a kind of impersonation attack where a legitimate user can create another valid pair of user identity and password without knowing the secret key of the remote system. However, an assumption under Chan and Cheng's attack is that the attacker must he a legal user. In this paper, we further present a more fundamental and efficient impersonation attack on Hwang and Li's scheme. Using our attack, any users (including legal and illegal users) can easily get a specific legal user's password, impersonate this specific user to login to the remote system, and pass the system authentication.
