Seongho Ju, Moonsuk Choi, Chunghyo Kim, Yonghun Lim


Advanced Metering Infrastructure (AMI) becomes one of the most realistic and commercial systems in power grid since smart grid has been introduced, but its security issues are not cleared yet because of both economical and technical problems. However, the infringement of privacy becomes under controversy recently, security cannot be an option in deploying AMI system any more. In this paper, we propose the security architecture for AMI system after defining some security requirements, and then the AMI security protocol in more details. The emulation board is implemented in FPGA type to verify that our research is reasonable and realistic.
