The improvement of ID-based remote user authentication scheme using bilinear pairings
Yi-Pin Liao, Chih-Ming Hsiao · 2011
Bilinear pairings in cryptography have been found to be very useful for various applications recently. In 2006, Das et al. proposed a novel ID-based remote user authentication scheme using bilinear pairings. The ID-based public-key cryptosystem (ID-based PKC) with bilinear pairings defined on elliptic curve can achieve simplifying the certificate management. However, Das et al.'s scheme cannot provide mutual authentication and session key agreement. Furthermore, Das et al.'s scheme suffers from the forgery attack. Since that, some ID-based remote user authentication schemes with smart cards using bilinear pairings are proposed to enhance the security of authentication system. In this paper, we observe that most published pairing-based authentication schemes are vulnerable to specific offline dictionary attack. Thus, we propose an improved ID-based remote user authentication scheme using bilinear pairings. We make security analysis based on Fang et al.'s security requirements. It proves that the proposed scheme can be used widely than other pairing-based remote user authentication schemes in unsecured communication environments.
