The study introduces the novel message authentication schemes for smart meter system, where symmetric cryptography-based physical layer-assisted (PLAA) scheme and public key infrastructure- based PLAA are introduced. proposed integrate conventional layer mechanisms by taking advantage of temporal spatial uniqueness in channel responses, aiming to achieve fast while minimising packet transmission overhead. authors also verify their claims through extensive analysis simulation via comparing with traditional upper schemes. yield lower time delay authenticating each message, which can satisfy requirement real-time control over grid.
