Embedded secure measurement and control system for smart home based on SMS4- CCM algorithm

智能家居逐渐实现了从单一智能产品向网络化集成系统的转变,却面临着更加凸显的智能家居测控信息安全风险。为了保障智能家居测控网络的可靠操控和隐私安全,提出并建立了嵌入式服务器和Zig Bee传感网结合的智能家居安全测控系统,采用IEEE地址过滤的白名单设备入网机制、基于SMS4-CCM算法的通信保密机制,实现远程用户安全接入、入网设备认证、测控指令加密传输及入侵检测报警等功能。基于ARM-LINUX平台实现了基本的智能家居嵌入式安全测控系统,测试结果表明:该方案能够对智能家居设备进行有序地网络化测控,可有效抵御智能家居面临的安全威胁并实时报警,且应用国产SMS4算法的系统性能更好,有助于保障智能家居系统安全可靠地运行。

Smart home has been gradually transformed into networking integrated system from single intelligent unit,while it is facing more and more outstanding risks of information security in measurement and control among smart home. In order to ensure the reliable operations and privacy of measurement and control network for smart home,a secure measurement and control system for smart home is proposed and constructed,which combines with an embedded server and a Zig Bee sensor network. This system adopts access control mechanism with the white list device based on IEEE address filtering and secret communication one based on SMS4-CCM algorithm to realize remote user access,authentication of incoming device,encrypted transmission of measurement and control instructs,intrusion detection and etc. A basic embedded secure measurement and control system for smart home base on the ARM-LINUX platform has been set up. The test results show that the devices in smart home can be orderly measured and controlled by network,meanwhile,it can effectively withstand the threat aiming at smart home and give out a real-time alarm. Meantime,the performance of system applied the domestic SMS4 algorithm is better. This is helpful to guarantee that smart home system securely and reliably runs.
