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...
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 ...
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...
Recently, Yang et al. improved Yang and Shieh's two password authentication schemes to withstand Sun and Yeh's forgery attacks. However, Kim et al. pointed out that Yang...
