Smart home security issues based on the Internet of Things
Abstract：With the vigorous development of IoT technology, the Smart home industry is about to usher in an era of rapid development. Due to the particularity of smart home usage scenarios, the corresponding security and privacy issues have become more prominent,attracting more and more researchersrsquo; attention. At present, the research on the security issues related to the application of the Internet of Things in Smart homes is still in its infancy. Most of the research results are not comprehensive enough to solve the security issues in the development of the Internet of Things. This article first explains the development history and status quo of Smart home and the Internet of Things; Then analyze and discuss security issues such as identity authentication, intrusion detection and other security issues involved in the application of the Internet of Things in Smart homes (home security, home equipment control, environmental monitoring); Then through a detailed analysis of the current five major IoT security issues in Smart homes: active attacks on computer networks, IoT architecture security, data privacy security, terminal device security, and communication security. Finally, summarize the current challenges and opportunities in the development of the Internet of Things security for Smart homes, so that Smart homes can provide people with a happy and safe living environment.

1 研究目的与意义
5G时代的到来给智能家居的发展带来了更优越的环境，智能家居行业即将迎来高速发展的时代。智能家居是依托于物联网的一种家居设备，因此相应的物联网应用越发普及，但近年来物联网安全问题频频出现，引起了越来越多研究者的关注。[2]物联网与人类社会的联系愈加紧密，一旦物联网安全受到威胁，就可能会导致社会正常秩序受到破坏，影响巨大。现在智能家居设备经历智能单品阶段，目前处于智能互联阶段，在向着主动智能方向发展。在智能互联阶段，大部分设备通过WIFI连接，只要攻破WIFI连接，就能控制整个智能家居系统。所以智能家居和物联网发展面临的最大的问题就是安全威胁和个人隐私泄露的问题。[3]
