Application and Research of Mobile E-commerce Security Based on WPKI

In order to solve the data integrity, non-repudiation, confidentiality and operation inefficiency of the mobile e-commerce, in this paper, mobile e-commerce security model is established. The design is based on mobile e-commerce architecture, analyzing the digital signature authentication process and data security transmission procedure in the system. Delamination modularized software design method is applied, and simulation results is carried out in the system based on OPNET and C++. The system adds the WIM smart card in the mobile terminal, and uses elliptic curve cryptography (ECC) encryption arithmetic, it complete the data encryption integrity authentication personal identification fast. By analysis of the procedure of the system and simulation results, the system has the advantage of fast operation, high security and high channel availability, which can satisfies the basic needs of mobile e-commerce.
