Abstract
Customers' privacy and messages integrity are the main security challenges for home area networks (HANs) in the smart grid, especially during the electricity consumption aggregation. In addition, smart meters and smart appliances, which are the limited-resources home devices, cannot implement complex computation operations. In this paper, we propose a lightweight privacy-preserving aggregation scheme that permits the smart appliances to aggregate their readings without involving the smart meter. The scheme deploys a lightweight lattice-based homomorphic cryptosystem that depends on simple addition and multiplication operations. Security analysis and performance evaluation demonstrate that the proposed scheme guarantees the customers' privacy and message integrity with lightweight overhead.
