MARTINEZ-PELAEZ, Rafael; RICO-NOVELLA, Francisco  and  VELARDE-ALVARADO, Pablo. Security Enhancement on Li-Lee's Remote User Authentication Scheme Using Smart Card. Comp. y Sist. [online]. 2014, vol.18, n.4, pp.709-717. ISSN 1405-5546.

Recently, Li and Lee proposed a new remote user authentication scheme using smart card. However, their scheme requires a verification table and the user's identity is not protected. Moreover, users cannot change their password off-line. In order to overcome the security flaws, we propose a new scheme which provides more security without affecting the merits of the original scheme.

Keywords : Cryptanalysis; mutual authentication; network security; session key; smart card.
