Abstract

Recently, the interest in green energy is increasing as a means to resolve problems including the exhaustion of the energy source and, effective management of energy through the convergence of various fields. Therefore, the projects of smart grid which is called intelligent electrical grid for the accomplishment of low carbon green growth are being carried out in a rush. However, as the IT is centered upon the electrical grid, the shortage of IT also appears in smart grid and the complexity of convergence is aggravating the problem. Also, various personal information and payment information within the smart grid are gradually becoming big data and target for external invasion and attack; thus, there is increase in concerns for this matter. The purpose of this study is to analyze the security vulnerabilities and security requirement within smart grid and the authentication and access control method for privacy protection within home network. Therefore, we propose a secure access authentication and remote control method for user’s home device within home network environment, and we present their security analysis. The proposed access authentication method blocks the unauthorized external access and enables secure remote access to home network and its devices with a secure message authentication protocol.

Summary

Introduction

The smart grid with which studies are being actively conducted based on recent convergence technology is called intelligent electrical grid and great attention is paid to it as the technology for the accomplishment of low carbon green growth. Smart grid is a power infrastructure system of the generation linked to smart demand management and new renewable energy by applying IT to the existing electrical grid and exchanging real-time information both ways between supplier and consumer. Combining IT technologies to the existing electrical grid systems can enable power supplier and consumer to obtain useful information from each other on real-times basis, and this can maximize the energy efficiency of the whole electrical grid systems. Two-way information exchange infrastructure between power suppliers and consumers called AMI (advanced metering infrastructure) can be considered as the core of smart grid [1–3]. For the diversity in rate plan, more selection for consumer, and the creation of new service to result from the application of AMI, the replacement from mechanic watt-hour meter to smart meter is essential. The base for optimization in energy use can be arranged through real-time confirmation on one’s own electricity use and rate and the control by automated remote device [4]
