随着智能家居、智慧医疗、车联网等技术的发展,物联网应用越发普及,在5G的牵引下,物联网有了新的发展动能,连接总数持续稳步增长,同时物联网安全攻击数量也空前增长,因此网络安全问题也引发了众多研究者的关注.首先介绍了物联网安全态势,然后基于物联网的网络架构系统阐述了物联网纵深安全体系.最后针对国际电信联盟无线电通信部(International Telecommunication Union-Radiocommunication Sector,ITU-R)中定义的大规模机器通信(Massive Machine Type Communication,mMTC)场景所面临的安全问题进行了阐述与分析.
Analysis of the security threats and defense system for the Internet of Things and research on security issues in 5G mMTC scenarios
With the development of smart home,digital medical,Internet of vehicles and other technologies,the application of the Internet of Things is becoming more and more popular.The traction of 5G makes the Internet of Things gain new momentum for devel-opment,the total number of connections continues to grow steadily,and the number of security attacks of the Internet of things also in-creases unprecedensively.Therefore,the issue of network security has attracted the attention of many researchers.Firstly,the security situation of the Internet of Things is introduced,and then the in-depth security system of the Internet of Things is described based on the network architecture system of the Internet of Things.Finally,the security problems of mMTC scenario defined in ITU-R are ex-pounded and analyzed.
