In 2002, Chien et al. proposed an efficient remote authentication scheme using smart cards, in which only few hashing operations are required. Later, Ku et al. gave an improved sc...
Recently, Lee, Ryu and Yoo proposed a fingerprint-based remote user authentication scheme by using smart cards and biometrics. Their scheme is based on two tiers of ElGamal's...
This paper presents a detailed review of remote user authentication schemes with smart cards based on bilinear pairings. The first scheme regarding this was proposed by Manik et a...
In 2005, Yang, Wang, and Chang proposed an improved timestamp-based password authentication scheme in an attempt to overcome the flaws of Yang-Shieh's legendary timestamp-base...
Abstract—In this work we consider two protocols for performing cryptanalysis and security enhancement. The first one by Song, is a password authentication scheme based on smart ...
