智能家居物联网的安全性设计与验证

智能家居作为物联网的重要应用方向之一，在带给人们居家方便的同时伴随着安全隐患。为了杜绝可能存在的潜在混乱，提出并建立了基于SM4密码算法的智能家居物联网安全系统，集成入网密钥验证、系统控制指令保密传送以及入侵检测报警等安全机制；在此基础上，对安全的智能家居物联网系统进行了验证性实现。测试结果表明，该方案能够有效地提升智能家居物联网系统的安全性，可阻止针对智能家居网络的恶意攻击、及时发现入侵并报警。

Design and implementation of security-focused intelligent household Internet of things

As one of important applications of the Internet of things(IOT), the intelligent household network brings people convenientce, meanwhile, with hidden dangers in secure control of network. To prevent the potential confusion, a systematic architecture based on SM4 algorithm of encryption for intelligent household IOT security is proposed; it integrates the access key authentication mechanism, the encrypted transmission of control instructions of system, and the mechanism of alarm on invasion. Furthermore, a proving intelligent household IOT security system is built. The results show that the proposed method can be applied to the intelligent household IOT and effectively improving the security of the system; it is able to prevent adversary from attacks, to timely discover invasion against the intelligent household IOT and alarm.
