Security mechanism for distribution automation using EPON

Abstract

In electrical power industry, a reliable communication network constitutes the core of the distribution automation system (DAS). This paper first proposes a novel communication method for distribution automation using Ethernet Passive Optical Networks (EPON). Then, based on the symmetric cryptographic techniques, a secure DAS communication architecture is presented. Following the standard registration procedure, the mutual device authentication between the OLT and the ONU is finally implemented.
