Abstract
Recently, the security of Smart Grid has become an important issue. There are many security issues which should be addressed. With that, many previous studies have discussed these issues. However, most of them focus on the overall Smart Grid system rather than the Home Network Area (HAN) in Advanced Metering Infrastructure (AMI) network. The HAN has become a critical issue of Smart Grid due to save energy and to reduce energy peak loading. In-Home Display (IHD) is a useful device in the HAN. Therefore, in this paper, we design a secure authentication protocol between IHD and Head End. The protocol is compatible with IEC 62056-53 which is a Smart Grid standard. Furthermore, the proposed authentication is the first protocol which takes the relationship between landlord and tenant into account. We leverage a cellphone to accomplish this purpose. In this paper, the security analysis of the proposed protocol is also given. © 2012 Springer Science+Business Media.
