چکیده

In 1995, Wu proposed a remote login authentication scheme based on geometric approach. However, Chien, Jan and Tseng presented a cryptanalysis of Wu’s scheme to show that it is not secure. Moreover, they proposed a modified version of Wu’s scheme. This paper presents there is a serious weakness in this modified remote login authentication scheme. We show that an illegal user can easily forge a valid login request in the modified version proposed previously.

Cryptanalysis of a Novel Remote User Authentication Scheme

In 2005, Manik et al. [5] propose a novel remote user authentication scheme using bilinear pairings which allows a valid user to login to the remote system but prohibits too many users to login with the same login-ID. It also provides a flexible password change function. In the same year Chou et al.’s [3] proposed an impersonation attack on their user authentication scheme and also proposed the...

A Remote User Authentication Scheme using Bilinear Pairings

In 2006, Das et al. [6] proposed a novel remote user authentication scheme using bilinear pairings. In that scheme, the remote system receives user login request and allows login to the legitimate user. In this paper we present the cryptanalysis of the Das et al. scheme and propose an improved and more secure scheme that enables user to choose and change their password without the help of the r...

Cryptanalysis on Tan-Zhu Remote Password Authentication Scheme

In 1999, Tan and Zhu proposed a remote password authentication scheme that is the first remote login scheme using smart cards based on cross product of matrixes. The scheme is efficient and flexible as compared with other matrix-based remote authentication schemes. However, Chien, Jan, and Tseng have shown that an attacker can impersonate a legitimate user to login the system in the scheme. Thi...

Cryptanalysis and Improvement on Robust Three-Factor Remote User Authentication Scheme with Key Agreement for Multimedia System

A three-factor authentication combines biometrics information with user password and smart card to provide security-enhanced user authentication. An proposed user authentication scheme improved Das’s scheme. But An’s scheme is not secure against denial of service attack in login phase, forgery attack. Li et al. pointed out them and proposed three-factor remote user authentication scheme with ke...

Cryptanalysis of a Timestamp-Based Password Authentication Scheme

Recently, J.-J. Shen, C.-W. Lin and M.-S. Hwang (Computers & Security, Vol 22, No 7, pp 591-595, 2003) proposed a modified Yang-Shieh scheme to enhance security. They claimed that their modified scheme can withstand the forged login attack and also provide a mutual authentication method to prevent the forged server attack. In this paper, we show that the Shen-Lin-Hwang scheme cannot resist the ...
