5G的mMTC场景下的物联网感知层的认证安全

第五代移动通信技术(The 5th Generation Moblie Communication,5G)的大规模商业化部署正在进行中,5G三大应用场景之一的大规模机器通信(massive Machine Type Of Communication,mMTC)为物联网技术提供了诸如智能家庭、智慧城市等新的应用场景。其设备种类多、数量多和规模大等特性对于应用在该场景下的物联网感知层设备的认证安全提出了更多的要求。本文简要分析了mMTC场景下的物联网设备通信特性对物联网感知层设备认证的安全需求,并从当前信息安全研究的热点中选取了有希望解决或改进这些安全需求的方法进行简要地分析。

The large-scale commercial deployment of the fifth-generation mobile communication technology (5G) is underway.The massive machine type of communication (mMTC),one of the three major application scenarios of 5G,provides Internet of Things (IoT) technology with new application scenarios such as smart homes and smart cities.The IoT equipments of mMTC has the characteristics of large verities,quantity and scale.These characteristics bring up more security requirements to the authentication security of IoT perception layer equipments used in mMTC scenario.This paper briefly analyzes the security requirements of authentication security of IoT devices in the mMTC scenario,and selects methods that may solve or improve these requirements from current research hotspots of information security and briefly analyzes them.
