摘要: 非侵入式负荷监测技术有助于用电精细化管理,但细粒度的电力消费数据也导致了用户隐私信息暴露在攻击者面前。首先分析了非侵入式负荷监测数据所面临的安全风险,并从密码学角度提出了基于AES+RSA的混合加解密信息安全方案。方案采用对称算法AES加密数据、非对称算法RSA加密AES密钥来实现高效的密钥管理。利用Visio Studio 2017+Qt软件开发测试界面,通过数据总线将算法写入STM32单片机进行方案性能测试,优选出最佳的运行模式,同时验证了混合加解密方案的有效性。总结得到,方案的耗时长短取决于RSA算法的加解密或签名验签的效率。

Abstract: Non-invasive load monitoring technology is helpful to fine management of electricity consumption, but the fine-grained power consumption data also leads to the exposure of users′ private information to attackers. This paper firstly analyzes the security risks faced by non-intrusive load monitoring data, and proposes a mixed encryption and decryption information security scheme based on AES+RSA from the perspective of cryptography. In this scheme, symmetric algorithm AES is used to encrypt data, and asymmetric algorithm RSA encrypts AES keys to realize efficient key management. Using Visio Studio 2017+Qt software development and test interface, the algorithm was written to STM32 microcontroller through the data bus for scheme performance test, the best operation mode was optimized, and the effectiveness of the mixed encryption and decryption scheme was verified. It is concluded that the time of the scheme depends on the efficiency of RSA encryption and decryption or signature verification.
