Since 2004, several user authentication schemes purpose to provide user anonymity in wireless communication have been announced, however, many of them failed to provide user anonymity, actually. In 2011, Li and Lee proposed a secure user authentication scheme for wireless communications. Differently from the previous researches, Li and Lee claimed two more session keys to enhance entire security of the scheme. However, to fulfil their claim, Li and Lee adopted Diffie-Hellman key agreement method in their scheme, and it required plenty of resources. Thus, in this paper, we point out inefficiency of Li and Lee’s scheme and propose a more efficient user authentication scheme for wireless communications.
