Research On Key Technologies Of Mobile Payment System Security

The security of mobile payment system directly affects the healthy development of the mobile business. This paper studies four aspects of security of mobile payment system in depth, which includes system architecture, identity authentication, fair payment protocol, risk assessment of system security. Firstly, after analyzing the existing architecture of mobile payment system we construct the architecture of mobile payment system with tolerate mechanism, based on mobile payment proxy server model. Secondly, applying the elliptic curve cryptography mechanism, the dynamic authentication scheme is established, based on STK card. Thirdly, in order to avoid the defects of abuse information and no accountability in fair payment protocol of electronic payment, a fair payment protocol is designed, according to the concurrent signature mechanism. Finally, after determine the evaluation indexes of mobile payment system by components, we apply Etenics theory to comprehensively evaluate the security of mobile payment system, which can scientifically and objectively reflect the real situation.
