In this paper, we propose a mutual authentication scheme using nonce variable instead of Mac address and accompanying with token updates to improve the functionality. Lee et al. (2...
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...
We propose two constructions of chosen-ciphertext secure identity-based encryption (IBE) schemes. Our schemes have a security proof in the standard model, yet they offer performan...
Recently, bio-information has been playing an important role in modern user authentication schemes. In 2004, Lin and Lai proposed a flexible biometrics remote user authentication s...
Recently, Tian et al. presented an article, in which they discussed some security weaknesses of Yoon et al.'s scheme and subsequently proposed two "improved" scheme...
