摘要
智能家居面临日益严重的数据安全问题,提出一种无线组网智能家居系统及其安全通信方法,即设计组网方案,采用WiFi和ZigBee无线技术通信。家居设备节点采用ZigBee通信方式,其他设备采用WiFi通信方式。结合MQTT协议设计安全通信方案,路由器部署为MQTT服务器,并进行安全配置;家居控制设备为MQTT客户端,使外网中的控制设备可以采用安全内网穿透方案ZeroTier访问内网。同时,提出基于L-P混沌系统交叉扩散方法产生AES初始轮密钥,并用于ZigBee安全通信。实验结果与分析显示,所提通信方法安全,与标准AES算法相比,运行时间相似,分别为0.628、0.633 s本文方法所需时间更短,具有可用性。
For the increasingly serious data security problems faced by smart home,a wireless networking smart home system and its secure communication method are proposed.Firstly,the networking scheme is designed,based on WiFi and ZigBee wireless technologies,mainly.Among them,the home device nodes adopt ZigBee communication mode,and other devices adopt WiFi communication mode.Then combined with MQTT protocol,a secure communication scheme is designed.The router is deployed as an MQTT server and configured for security.The home control devices are as MQTT clients,so that the control devices in the external network can access the internal network using the secure internal network penetration scheme of ZeroTier.At the same time,the cross diffusions method based on L-P chaotic system is proposed to generate AES initial round key,and achieve ZigBee secure communication.The experimental results and analysis show that the proposed communication method is secure,and compared with the standard AES algorithm,the running time is similar,which is 0.628 s and 0.633 s respectively.The method in this paper Costs less running time,so it is available.
