The authors present a new remote user authentication scheme on three dimensions for multi-server environments. The merits include: the scheme can be used in multi-server environments; the system does not need to maintain any verification table; the users who have registered with various servers do not need to remember different login passwords for each; the ability to choose passwords freely and change them offline; mutual authentication is provided between the user and the remote system; a session key agreed by the user and the remote system is generated in every session. Furthermore, we propose a specific Access Right (AR). The AR means the legal users have different level of authorization based on which server in the multi-server environment in used.

<p>Wu-Chieu proposed an enhanced remote user authentication scheme to improve the security of a user-friendly remote user authentication scheme with smart cards. However, we demonstrate that their scheme is vulnerable and susceptible to the attacks and can easily be cryptanalyzed. Their scheme performs only unilateral authentication (only client authentication) and there is no mutual authentication between user and remote system, so their scheme suscepts from the server spoofing attack. Furthermore, their scheme is slower in detecting the wrong input-password, and users cannot change their passwords. This paper proposes an efficient and secure remote authentication scheme to solve the problems found in Wu-Chieu’s scheme. In addition, the computational costs and efficiency of the proposed scheme is better than other related published schemes.</p>

Three Factor

Recently, Om et al. proposed three-factor remote user authentication protocol using ElGamal cryptosystem and ensured that it is withstands to various kinds of security attacks. But, the authors review carefully Om et al.'s scheme and discover that it unable to resist three attacks (like password guessing; denial of service; and user impersonation). Moreover, their protocol is not facilitating user anonymity. To solve these security vulnerabilities, the authors devise a secure and robust anonymous identity based authentication scheme for multi-server environment. The authentication proof of the proposed scheme has validated using BAN (Burrows-Abadi-Needham) logic, which confirms the protocol facilitates mutual authentication and session-key negotiation securely. Informal security analysis also confirms that it is well protected against various security attacks. In addition, the proposed work is compared along with other schemes (in the context of smart card storage and computation costs as well as execution time).
