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.
基于轻量级格的家庭区域网络同态隐私保护聚合方案
用户隐私和消息完整性是智能电网中家庭区域网络(HANs)面临的主要安全挑战,特别是在用电聚合过程中。此外,智能电表和智能家电作为资源有限的家居设备,无法实现复杂的计算运算。在本文中,我们提出了一种轻量级的隐私保护聚合方案,该方案允许智能设备在不涉及智能电表的情况下聚合它们的读数。该方案部署了一个轻量级的基于格的同态密码系统,它依赖于简单的加法和乘法运算。安全性分析和性能评估表明,该方案在保证用户隐私和消息完整性的同时,开销很小。
