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.
