Abstract :
In 2012, Wen and Li pointed out the weaknesses of Wang et al.´s scheme, then, they proposed a dynamic ID-based remote user authentication scheme to improve it. They claimed the proposed scheme having fixed it the weaknesses pointed to. However, the proposed scheme still has a weak point, anonymity, a scheme claimed dynamic ID-based must propose to be had. in this paper, we improve its anonymity.
