Research on dynamic trust evaluation mechanism of MAC layer in G3-PLC

G3-plcis a widely used and promising power line communication standard protocol, which plays an important role in energy measurement in smart grid. This paper studies the carrier communication security in G3 standard power line carrier layer. The perception layer is added to the MAC sub-layer, and the dynamic trust evaluation mechanism model is designed to allocate the spectrum resources of users. By using reinforcement learning method, the server allocates the spectrum resources of the client according to the trust value, and finally the malicious users are eliminated from the whole network.
