摘要
在智能电网中,智能电表发送的用电信息可能被窃听,从而导致用户隐私的泄露。为解决该问题,文章提出一种智能电表安全通信方案。该方案基于对称加密算法,其主要安全特性包括设备认证、数据机密性和完整性,并通过安全数据聚合保护用户隐私。经过安全性分析表明,该方案可以达到智能电表通信的安全需求并抵抗常见的安全威胁。
In smart grid, the power usage data sent out by smart meters may be eavesdropped, which leads to user privacy leakage. To solve this problem, a secure communication scheme for smart meter is proposed in this paper. The scheme is based on a symmetric cryptosystem, whose main security features include device authentication, data confidentiality and integrity. Specially, user privacy is protected through secure data aggregation. Security analysis is provided to demonstrate that the scheme can meet the security requirements of smart meter communications and resist common security threats.
