基于SOPC的GPS信息加密传输系统

Design of GPS data encryption communication system based on SOPC

设计了一个GPS信息加密传输系统,用于车辆、人员等重要移动目标的远程监控。该系统主要由一台中心计算机和一组终端模块组成,前者负责定位信息的接收、处理、显示以及密钥分发等系统管理任务,后者安装在被监控的移动目标上,负责定位及其它监控信息的加密传输,中心计算机与终端模块之间采用CDMA进行无线通信。终端模块利用商用GPS接收模块实现定位信息采集,采用基于Alera FPGA的SOPC技术,实现了整个终端模块的控制和数据加解密。

A GPS data encryption communication system is presented,which can be used for monitor and control of vehicle for money escort and other important mobile equipment or personnel.It is composed of a center computer,which is located in headquarter,and a group of terminal modules.The first is responsible for the receiving,processing and display of information of all mobile objects,encrypt key distribution and other system management work.The second that is installed on the mobile object,take responsibility for the collection,encryption,transmission of GPS and other data of the mobile object.The wireless communication of the center computer and the terminal module is CDMA channel.The GPS data is acquire through GPS receiving module.The control of the terminal module and data en-cryption/decryption are realized by a SOPC,which is based on an Altera FPGA.
