Recently, many user authentication schemes using smart cards have been proposed to improve the security weaknesses in user authentication process. In 2008, Liu et al. proposed a new mutual authentication scheme using smart cards which is based on nonce and can withstand the existing of forged attack. In this paper, we analyze the security weaknesses of Liu et al.’s scheme. Although Liu et al.’s scheme overcame the vulnerability of Shen et al.’s scheme, we have shown that Liu et al.’s scheme is still insecure against the Impersonation attack and password guessing attack, and does not provide the mutual authentication between the user and the remote server.
