With the rapid growth of electronic commerce and demand on variants of Internet based applications, the system providing resources and business services often consists of many servers around the world. So far, a variety of authentication schemes have been published to achieve remote user authentication on multi-server communication environment. Recently, Pippal et al. proposed a multi-server based authentication protocol to pursue the system security and computation efficiency. Nevertheless, based on our analysis, the proposed scheme is insecure against user impersonation attack, server counterfeit attack, and man-in-the-middle attack. In this study, we first demonstrate how these malicious attacks can be invoked by an adversary. Then, a security enhanced authentication protocol is developed to eliminate all identified weaknesses. Meanwhile, the proposed protocol can achieve the same order of computation complexity as Pippal et al.'s protocol does.
