LPMP: An efficient lightweight protocol for mobile payment

The unprecedented development in wireless and mobile communication has brought forward incredible opportunities for mobile commerce. However the limited processing power, memory, power consumption of mobile devices and security aspects of wireless network are some of the major challenges in expanding mobile commence especially in developing country. In the present paper, an efficient protocol for mobile payment system is proposed that is based on a shared secret between the client and its bank/financial institution. While the protocol possesses all the requisite properties namely - privacy, integrity, authentication and non-repudiation, it minimizes the processing and memory requirement at the client end that makes it especially suited for low end mobile devices.
