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. InHome 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

In-home display AMI Smart grid
1 Introduction A Smart Grid is proposed to enable energy savings and carbon emissions reductions. It is a digitally enabled electrical grid with communication ability. Also, it could gathers, distributes, and acts on information about the behavior of suppliers and consumers to improve the efficiency, reliability, economics, and sustainability of electricity services. In general, Smart Grid infrastructure includes power station, power substation, transmission line and Advanced Metering Infrastructure (AMI). AMI is viewed as the foundational building block and it enables a two-way communication between a utility and its customers and interconnections to distributed energy resources. In this infrastructure, the electrical meters are replaced with smart meters to achieve two-way communication function. Through this equipment, utility can rapidly receive consumers energy usage information. Rely on this information, utility could estimate or predict the total energy consumption to make energy generation efficient. Further, smart meters could communicate with in-home displays (IHDs) to make consumers more aware of their energy usage. Choi et al. though that the smart metering system is as an effective method for improving the pattern of power consumption of energy cons
