Research On Mobile Electronic Commerce Security Model Based On WAP

Mobile Electronic Commerce is a new type of e-business. It developed with the technology of the mobile communications and the Internet. As an excellent business mode, the mobile electronic commerce have many virtues such as lower cost, higher security and deal at anytime and anywhere ,and so on. Its emergence will contribute greatly to the development of Electronic Business.Presently, many systems with regard to the mobile electronic commerce have been developed. However, researches on mobile electronic commerce are in a phase of exploring in our country. So it is of great importance to research the new type of mobile electronic commerce with full functions, and how to guarantee the security on the mobile electronic commerce system is the focus of research.The WAP protocol, which is put forward by the WAP forum, is thought as the ideal solutions in the security and efficiency for the mobile electronic commerce system. By analyzing the security of the WAP protocol, the thesis shows the WAP application model and the protocol structure, especially at the WTLS protocol that safeguards the security of the whole protocols, and makes some improvement at the handshake protocol. The WAP gateway is very important for the protocol conversion between the wireless and the Internet. Now there are many gateway models as WAP Server. WPKI is the extension of the PKI technology in the wireless field. Regards to the characteristic of the wireless communications, it adopts the new encryption algorithm and the new WTLS certificate. And these methods improve the efficiency of the encryption and the decryption, and reduce the bandwidth of transmitting the certificate. After introducing some common PKI trust models, the thesis provides a new trust model which is based on the grey theory. At last, the thesis gives the composing and the payment flow of the mobile electronic commerce system which is based on the WAP protocols.
