Recently, the Internet of Things system (IoT) in the power distribution station area has gradually developed towards intelligence. However, due to the existence of numerous low-voltage end-sensing units in the power distribution Internet of Things, these devices have limited computing resources and weak protection, which poses great security risks to the entire intelligent power distribution IoT. Therefore, this scheme studies a remote attestation mechanism for power distribution IoT terminals based on trusted measurement. This mechanism measures the trust of the power distribution station area terminals in multiple dimensions, including static environment and dynamic behavior. Then, these trust values are integrated into a comprehensive trusted measurement through information entropy. The simulation results show that this scheme can truly reflect the trusted status of terminals and accurately and effectively detect malicious nodes.
