Abstract

The invention discloses a TEE-based power Internet of Things secure communication module improvement method, which comprises a signal matching module, a communication processing module, a common operating system and a secure operating system. The signal matching module is electrically connected with the communication processing module and the common operating system, the signal matching module is used for detecting the air interface signal strength, the signal matching module feeds back a signal matching result to the communication processing module, and the communication processing module guides the signal matching module to carry out signal strength detection. The Trustzone technology used by the TEE-based power Internet of Things secure communication module improvement method is a widely used technology, can provide a trusted execution environment for intelligent equipment, can accord with the development of the power Internet of Things, provides a terminal-level security design and can implement a secure storage and transmission protection strategy, the security problem of key information processing is solved, and the secure communication of the power Internet of Things equipment terminal is realized.

Description

technical field [0001] The invention relates to the technical field of electric power Internet of Things security, in particular to a method for improving a TEE-based electric power Internet of Things security communication module. Background technique [0002] On the premise that the State Grid Corporation of China announced the construction of the "three-type and two-network" system, according to the development opinions of the State Grid Corporation of China, by 2021, the ubiquitous power Internet of Things will be initially established throughout the company, and business collaboration and data connectivity will be basically realized. Unify the management of the Internet of Things, so that the smart energy comprehensive service platforms at all levels have basic functions, and support the development of power grid business and emerging business. As the information bloodline of the power industry, the power Internet of Things has opened up the information communication be...
