The term \"Smart grid\" can be described as the next generation electric power system. The metering data should be continuously examined for valid testing and this is one of the challenge for the authors' smart grid. In this paper, they analyze the problem of supporting multidimensional range queries on encrypted metering data. The problem is motivated by the applications of secure data outsourcing where a residential user may store his data on a cloud server in an encrypted form and want to execute queries using server's computational capabilities. When financial auditing is needed, an authorized requester can send its range query tokens to cloud server to retrieve the metering data.
