Account Based Mobile Payment by Diffie-Hellman Key Exchange Protocol

With the development on techniques of mobile communication, the daily activities benefit from these techniques more than ever. In order to make living more convenient, the mobile payment has been brought up in recent years. The consideration for carrying out the mobile payment is very difference from that in the wired electronics payment scheme because of the characteristics of mobile device. In this article we develop a mobile payment scheme that is based on reducing the operation of the device, and furthermore achieves the demands of security. It can create the session key for each transaction by means of using the “Diffie-Hellman key exchange” protocol. The use of the Message Authentication Code (MAC) can achieve the integrity of electronic commerce. Both of them do not need a large number of operations and complex algorithm so it can achieve the purposes of this investigation: a secure, convenient and light-computation scheme for mobile payment
