In recent years, with the application of Multi-access edge computing (MEC) technology in the power Internet of Things (PIOT), the power Internet of Things has gradually formed a development trend of large connections, wide coverage, real-time, and intelligence. However, the introduction of MEC makes the power Internet of Things involve more information transmission and data processing, and how to strengthen the preventive measures for data security and privacy protection is also a key challenge. Aiming at the problem that the edge nodes in the power Internet of Things are vulnerable to attacks, this paper proposes a network security strategy for the power Internet of Things based on cloud-edge collaboration. This strategy updates their respective trust values in real time through the communication and interaction between nodes, and quickly detects abnormal nodes in the network based on the trust values. At the same time, this paper implements the abnormal node detection smart contract proposed in this paper based on the Hyperledger Fabric blockchain platform. The experimental results show that the designed abnormal node detection smart contract accurately detects the abnormal nodes in the network, and successfully synchronizes the results with all nodes, effectively ensuring the operation security of the power Internet of Things.
