Baocheng Wang, Shan Li · Proceedings of the 2020 4th International Conference on Electronic Information Technology and Computer Engineering · 2020
NB-IoT is a branch of the Internet of things which develops rapidly and is widely used in recent years. It can be compatible with a variety of devices to report information quickly and issue commands accurately. It is the preferred form for enterprises and institutions to control their IoT devices completely. Business can be perfectly realized through system function design, but the attention on security is often neglect. The information transfer from devices to the platform, and then to the management system, which may have a large number of security risks. According to the characteristics of NB-IoT and security requirements, this paper analyzes the key points of data flow direction, and puts forward possible security threats and corresponding avoidance methods.
