Abstract

Mobile communications offer a wide variety of services to people. All mobile subscribers can use a mobile device to access various resources and conduct their business anytime from anywhere. This feature has contributed greatly to the rapid development of mobile commerce. In fact, the Personal Trusted Device (PTD, such as PDA or mobile phone) lacks of computing resources has become a problem in mobile commerce development. In this paper, we overcome the limited computation power of mobile device and involve a trusted proxy server to coordinate transactions such that the important computation requirements can still be accomplished. In this paper, we propose a server-aided signature scheme for mobile commerce. We base on the Diffie et al. scheme and involve the one-time password mechanism to establish session key in advance, and then download the initial parameters into the mobile devices as the communication parameters between the mobile user and the proxy server. The proposed scheme satisfies the issues of security, non-repudiation, fairness, anonymity, simplicity, and mobility.
