Abstract: In the mobile payment protocols, the client works on wireless devices possibly with limited computation capacities, power and security challenges. In order to satisfy the above properties, a new secure efficient mobile payment protocol is proposed. In this protocol, client and bank can be mutual efficient authenticated and the session key is established due to the shared offline pseudo-random number. The transaction between merchant and client can be processed quickly with the shared key which is the proof of non-repudiation. On the analysis of BAN logic and efficiency, the proposed protocol minimizes the computing and communication requirement of the client that makes it especially suited for mobile devices.
