摘　　要：针对当前移动支付业务对安全性能的需求,描述了一种用于支付的手机终端,采用移动支付协议和终端安全机制,既保证了移动支付数据的安全性,又减少了通信次数和费用.此外,由于手机终端有限的存储能力和无线通信网络有限的带宽导致在无线移动环境中采用数字证书是不适合的,因此提出了一种基于身份的tate配对数字签名方案.通过终端身份特征生成密钥,有效地降低了公钥密码系统中数字证书的分发和管理成本.该数字签名方案具有简单、有效的特点,适用于低带宽的无线环境和低性能的终端设备中.At present the security of mobile services cannot be satisfied with the special requirements of mobile payment. Then the paper proposes a mobile terminal using the payment protocol and the security scheme to construct the mobile payment. With the character of generating keys from identity itself, furthermore, the scheme uses the efficient identity-based signature from tate pairings in smart card instead of digital certificate mechanism because the distribution and the management of digital certificate are not easy in wireless networks. The proposed signature scheme is simple, efficient so that it will be suitable for an environment of finite bandwidth of wireless networks and low-capability equipment. Security and performance analysis show that the proposed mobile terminal not only protects the data security but also reduces the time consuming and the costs.
