Constructing Multi-level Safety System of Gas IoT which is Characterized by Cloud, Management and Terminals

Beijing Gas Group used the Internet of things technology to build its Internet of things cloud platform. In the field of intelligent gas metering management and intelligent gas pipe network management, it has created the first complete NB-IoT intelligent application case in the domestic urban gas industry. The multi-layer defense system constructed by the information security design from the intelligent terminal to the application system effectively guarantees the data acquisition and remote control process of the massive NB-IoT gas intelligent terminal. The Internet of things cloud platform as a whole refers to the technical requirements of three levels of national information security protection. The security management subsystem of the Internet of things supports hardware encryption on security chips and software encryption. It can flexibly combine symmetric and asymmetric algorithms that meet the national security standards according to the needs of various business scenarios, and realize the encryption, decryption and signature verification processing of various data.
