基于ZigBee的无线通讯加密系统设计

Design of Wireless Communication Encryption System Based on ZigBee

为解决不同设备之间控制器域网(CAN)总线数据的通讯问题,设计了一种将数字信号处理器(DSP)、CAN总线技术、ZigBee通讯技术三者结合的无线通讯系统,该系统通过ZigBee对CAN总线数据进行转发,并在DSP平台上通过数据加密标准(DES)算法对转发数据进行加密。介绍了该系统从软硬件设计到具体实现的详细过程,并进行了试验验证。

In order to solve the problem of communication of controller area network(CAN)bus data between different devices,a wireless communication system combining digital signal processor(DSP),CAN bus technology and ZigBee communication technology is designed.The system forwards CAN bus data through ZigBee,and encrypts the forwarded data through data encryption standard(DES)algorithm on DSP platform.The detailed process of the system from software and hardware design to specific implementation is presented and experimentally verified.
