Abstract
Advanced metering infrastructure (AMI) is an integral part of smart grid network that involves transmission of finest grain operational data of consumers' load profiles on wireless facilities. Unauthorised access to these data due to the vulnerabilities of wireless facilities may easily disrupt smart grid. Some of the existing schemes only focus on specific attack(s), leaving other attacks, and most of them cannot be used to secure energy profiles from different time of use without increasing communication overhead. In this paper, a provably lightweight security scheme to secure metering and information exchange and consumers' privacies irrespective of the attacking points and nature of the attacks is proposed for AMI. Our scheme ensures data security and cooperative aggregation among m number of consumers of the same service provider. The security analysis and performance evaluation of the scheme are also presented. The results illustrate that the approach secures metering at a low overhead.
