Security Authentication for Smart Substation Communication based on IEC 62351

摘要

An important feature of smart substation system is the communication of the various smart devices IED (Intelligent Electronic Digital), the network security issues become increasingly prominent with networked and standardized of the communication protocols, especially when IEC 61850 becoming development direction. In this paper, considered data and security communications standard of the power system IEC 62351's safety authentication requirements, as well as limited storage and computing power of IED, a protocol used between IED safety authentication-Secure Remote Password SRP protocol is proposed. The research result help improve data security transmission and authentication of smart substation. It is provide with reference value to the implementation of IEC 62351 in smart substation.
