With the rapid growth of information technologies, mobile devices have been utilized in a variety of services such as e‐commerce. When a remote server provides such e‐commerce services to a user, it must verify the legitimacy of the user over an insecure communication channel. Therefore, remote user authentication has been widely deployed to verify the legitimacy of remote user login requests using mobile devices like smart cards. In this paper we propose a smart card‐based authentication scheme that provides both user anonymity and mutual authentication between a remote server and a user. The proposed authentication scheme is a simple and efficient system applicable to the limited resource and low computing performance of the smart card

Recently, with rapid advances of mobile devices such as smart phone and wireless networking, a number of services using mobile device based wireless network have been explosively increasing. From the viewpoint of security, because wireless network is more vulnerable than wired network, strong security is required in wireless network. On the contrary, the security for mobile devices has to be efficient due to the restrictions of battery powered mobile device such as low computation, low memory space and high communication cost. Therefore, in this paper, we propose an efficient authentication scheme with mobile devices in wireless network environment. The proposed scheme satisfies security requirements for the service using mobile device and it is suitable in wireless network environment.
