MobiCash: A New Anonymous Mobile Payment System Implemented by Elliptic Curve Cryptography

The emerging wireless and mobile networks have extended electronic commerce to another research and application subject: mobile commerce. This creates new opportunities for customers to conduct business from any location at any time. One of the important uses of mobile applications is transforming the mobile phone into a mobile wallet with digital cash that supports both anonymity (as real cash) and security [3]. Hence, in this article we propose a scheme to support m-commerce transactions and provide fully anonymity for mobile users. Our scheme is based on 160 bit ECC, Whose security intensity is equal to 1024 bit RSA. The paper describes the model, infrastructure and details of the protocol. It also discusses the applying ECC on protocol, some implementation issues and restrictions in mobile payment systems.
