Transaction Security of Mobile Payments using IMEI Number and Call Back Technique

Growing of wireless networks and popularity of handheld devices such as mobile phones represents an incredible opportunity to give power to mobile devices as a payment device. Unfortunately, some problems like limitation of power, less powerful processor of mobile phones needs new suitable algorithm for mobile phone payment. Recently, many public key cryptography algorithms are presented for mobile payment . However, limited capabilities of mobile devices and wireless networks make these algorithms unsuitable for mobile network. In this paper a new security algorithm for mobile phones based on call back technique and one time password using IMEI number is developed .This algorithm provides the required security for mobile payment regarding resource restrictions. The simulation results on prototype data indicate the efficiency of the proposed algorithm. Keywords— call back, IMEI, one time password, security
