Application of Identity Identification Technology Based on Wireless Radio Frequency Signal Features in Power System

Due to the openness of the wireless communication system in the power system, the wireless communication is more vulnerable to malicious attacks than the traditional wired communication system. Based on the above problems, the equipment RF fingerprint identification technology scheme is proposed. This scheme collects the RF fingerprint of the existing devices, builds the neural network structure, imports the RF fingerprint data for training and obtains the identification model. It introduces the RF fingerprint of the device into the trained recognition model for testing, and obtains the identification results. This scheme does not require repeated tedious calculation, reduces the cost, and achieves a better identification rate with lower complexity.
