A Security Mobile Payment Plan Based On WAP And WPKI

Mobile Payment (MP) is proposed as a new approach for buying and selling in transactions, of which the goal is through wirelessly connected mobile devices, customers are entitled to conducting transactions anywhere at any time. Contrast with traditional payment mechanism, MP is more convenient and beneficial, and it constitutes an indispensable component of mobile commerce technology.Just as common wireless networking applications, MP system is in a sense vulnerable to attackers due to the openness of system architecture, handicapped capacity of hand-held devices in the system, and drawbacks of wireless environment which accommodates the system, such as limited bandwidth and high error rate. All of these make MP easy to be eavesdropped by malicious third-party users. Particularly, if the stolen information is sensitive such as bank pass-code, it will cause terrific devastation to involved customers.To address the above mentioned problems, in this dissertation we proposed a WAP and WPKI based security scheme for MP system, which solves the three major security issues in MP system– authentication between the two sides in a transaction, data secrecy, and denial of past activity. Meanwhile, our scheme improves the existing mobile payment approach by incorporating into it a bilaterally evaluation-based mechanism, which convenience the security of mobile payment system, and its prosperous development.
