Smart grid, envisioned as an indispensable power infrastructure, is featured by real-time and two-way communications. How to securely retrieve and audit the communicated metering data for validation testing is, however, still challenging for smart grid. In this paper, the authors propose a novel Privacy-preserving Range Query (PaRQ) scheme over encrypted metering data to address the privacy issues in financial auditing for smart grid. Their PaRQ allows a residential user to store metering data on a cloud server in an encrypted form.
