The advantage of mobile penetration enables mobile operators to provide value added service such as mobile banking, GPRS based interactive application and enhanced security in the internet bsanking etc. This however, requires robust End-to-End security solutions. Mobile banking is attractive because it is a convenient approach to perform banking from any where any time, but there are security concerns in the implementation which include problems with GSM network, SMS, GPRS protocols and security problems. In this paper an end-to-end security framework using PKI for mobile banking is proposed. Performance of the proposed model is presented in this paper.
