Security Research on J2ME-Based Mobile Payment

The emergence of mobile payment, a new direction of electronic payment, releases paying from all fetters in space. However, the security issue of mobile payment has been created. A program of mobile payment based-on J2ME is designed in this paper, and the process of payment take use of digital signature technology to ensure information to be secure. Calculation, storing and communicating are transferred to the static host in order to minimize the load of mobile phones. At the same time, the transaction information is encrypted by use of elliptic curve cryptosystem and multi-digital signature based on this algorithm. In the same security strength, this improved algorithm results in smaller overhead and delay to achieve higher security.
