Abstract
Cyber-Physical Systems (CPS) for smart grid is one of the key directions in developing power systems. However, the closely integrated physical and information networks bring new challenges to communication security. From the perspective of cooperative and secure communication, this paper proposes a blockchain identity-based approach to secure cooperative communications for smart grid CPS. Idle nodes are selected as relay transmission nodes on the transmitter side to overcome the severe blocking fading of millimeter waves. Cooperative jamming nodes are also selected to interfere with eavesdroppers to improve the secrecy capacity of the communication. To ensure that the selected nodes are trustworthy, the smart grid CPS verifies the security of the nodes through blockchain-based decentralized identity authentication. We use the Double Duel Deep Q Network (D3QN) algorithm to optimize cooperative node selection to maximize the total secrecy capacity of all target nodes. We provide detailed model-building and experimental simulation results that validate the effectiveness of the proposed approach.
