Research on ECP3 Mobile-Payment

With the development of Mobile-Commerce, mobile-payment turns up. However, compared with the m-commerce in China, mobile-payment is too weak to meet the needs. This paper comes up with the ECP3 Mobile-Payment Solution (Elliptic Curve based Proxy Payment Protocol), which is a proxy payment solution based on the Elliptic Curve Cryptography. Taking less memory and bandwidth makes ECP3 quite suit for mobile devices. When a customer requests a payment, the payment-chain starts. All the payment work will transfer to the MNO (Mobile Network Operator) to through the payment-chain. Then MNO checks both customer´s and the Application Service Provider´s identity. After that, MNO sends the payment info to customer for confirming. ECP3 is of security and efficiency, which can satisfy the M-Commerce´s distant payment requirement.
