Abstract
Smart grid is a modernized electrical grid. It is used to collect information about behaviors of suppliers and consumers and improve the efficiency, reliability, and economics of electricity. Recently, advanced metering infrastructure is proposed as a critical part of the smart grid. The security of advanced metering infrastructure is special importance for smart grid. In order to achieve data confidentiality, privacy, and authentication in advanced metering infrastructure, a lightweight authentication and key agreement scheme is proposed in this article. The scheme provides mutual authentication, key agreement, key refreshment, and multicast mechanism which can prevent various attacks. Furthermore, we analyze the security and performance of the scheme. The analysis shows that the proposed scheme is suitable for smart grid.
Highlights
Smart grid (SG) is designed to replace traditional electric power infrastructure and used to manage electricity demand in a sustainable, reliable, and economic manner
We present the scheme in section ‘‘The proposed scheme.’’ The security and performance analysis are given in sections ‘‘Security analysis’’ and ‘‘Performance analysis.’’ we draw our conclusion in the last section
We focus on secure mutual communication between the building area network (BAN) GW and SM in home area network (HAN)
Summary
Smart grid (SG) is designed to replace traditional electric power infrastructure and used to manage electricity demand in a sustainable, reliable, and economic manner. In 2011, a key distribution and management scheme for AMI was proposed by Kamto et al.[15] The aim of the protocol is to provide communication security between group of devices and SMs in HAN. We propose an authentication and key agreement scheme for SG.
