Abstract
최근 스마트그리드가 발달함에 따라 AMI망에서의 보안은 전력정보통신에 많은 변화를 주었다. 본 연구는 사이버 공격으로부터 AMI시스템과 제품사이에 연결되어있는 각각의 구성품을 안전하게 보호하고, 댁내와 사용자에게 발생할 수 있는 2차 피해를 막기 위해 설계되었다. AMI망에서의 보안문제를 해결하기위해 공개된 암호키를 기반으로 보안알고리즘을 구성하고 키를 생성하여, 새로운 AMI설비가 보호될 수 있도록 제안하였다. Recently with improvement of SMART Grid, AMI network security has been affecting the environment for Electric information and communication. The system and communication protection consists of steps taken to protect the AMI components and the communication links between system components from cyber intrusions. The addition of two way communications between SUN and HAN introduces additional risk for unauthorized access to the AMI system. In this paper, we propose new AMI device authentication infrastructure, key establishment and security algorithm based on public key encryption to solve AMI network security problems.
