Extremely Lightweight PUF-based Batch Authentication Protocol for End-Edge-Cloud Hierarchical Smart Grid

Smart grid is gradually replacing traditional with two-way communication and improved management. Besides the efficiency reliability it brings, smart inevitably fraught rampant physical cyber-attack. Although several unclonable function (PUF)-based schemes have been proposed, they are unsuited to end-edge-cloud hierarchical grid. This paper proposes a PUF-based batch authentication key agreement protocol, which protects both meters gateways provides end-to-end between server. By offloading heavy operations from field devices server, computation overhead reduced substantially. Moreover, we innovatively devolve access control gateway, additionally decreases downlink signaling cost, superior most recent schemes. Our protocol proved by Tamarin under extended Dolev–Yao adversary Real-or-Random model evaluated be secure against various attacks. Using extremely lightweight operations, our implemented on MSP430FR5969 microcontroller.
