Efficient Biometrics Remote User Authentication Scheme
نویسندگان
چکیده
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 scheme. However, their scheme is vulnerable and cannot provide mutual authentication between user and remote system. Hence, Khan and Zhang improved the security of a flexible biometrics remote user authentication scheme in 2007. This paper shows that Khan et al.’s scheme is still vulnerable to both the impersonation attack and the man-in-the-middle attack. Moreover, an efficient and flexible biometrics user authentication scheme is proposed to enhance the performance and correct the security problems.

An enhanced biometrics-based remote user authentication scheme using mobile devices
Remote user authentication is a mechanism, in which the remote server verifies the legitimacy of a user over an insecure communication channel. Recently, Wang and Li proposed a fingerprint-based remote user authentication scheme using mobile devices. We demonstrate that their scheme is vulnerable and susceptible to many attacks and has some practical pitfalls. To solve these problems, we propos...

Recently, Li and Hwang proposed an efficient biometrics-based remote user authentication scheme without storing the password tables. Their scheme uses random numbers to solve the problem of synchronized clocks. It also enables the user to freely choose or change their passwords. At the same time, they claimed that their scheme provides security, reliability and efficiency. However, we found tha...

In this paper, we propose an efficient biometric-based remote user authentication scheme using smart cards, in which the computation cost is relatively low compared with other related schemes. The security of the proposed scheme is based on the one-way hash function, biometrics verification and smart card. Moreover, the proposed scheme enables the user to change their passwords freely and provi...
متن کاملCryptanalysis and improvement of a biometrics-based remote user authentication scheme using smart cards
Recently, Li and Hwang proposed a biometrics-based remote user authentication scheme using smart cards [Journal of Network and Computer Applications 33 (2010) 1–5]. The scheme is based on biometrics verification, smart card and one-way hash function, and it uses the nonce rather than a synchronized clock, so it is very efficient in computational cost. Unfortunately, the scheme has some security...
