Security mechanism for smart distribution grid using Ethernet Passive Optical Network

A reliable communication network constitutes the core of the smart distribution grid. This paper proposes a novel communication method for distribution automation using Ethernet Passive Optical Networks (EPON). Then, based on the proposed communication infrastructure, and using the identity-based cryptography (IBC), a secure communication system for smart distribution grid is presented, where the mutual device authentication between the OLT and the ONU is implemented.
