Design and realization of identity-based mobile payment system
基于身份认证的手机支付系统的设计与实现

According to the bilinear property of the Weil pairing defined on elliptic curves and Euler's criterion, an identity-based signcryption scheme was proposed. The scheme could obtain the quicker velocity of encryption and decryption, distinguish the right message from the wrong message, and resist the attack of continuous cryptograph sending. This scheme could reduce the storing and managing cost of the public key. The signature size was only about a quarter of the Guillou-Quisquater signature. Based on the signcryption algorithm and the properties of the mobile, a new mobile payment system was proposed. Its security and efficiency performances were also analyzed.
