摘要: 非侵入式負荷監(jiān)測技術有助于用電精細化管理,但細粒度的電力消費數據也導致了用戶隱私信息暴露在攻擊者面前。首先分析了非侵入式負荷監(jiān)測數據所面臨的安全風險,并從密碼學角度提出了基于AES+RSA的混合加解密信息安全方案。方案采用對稱算法AES加密數據、非對稱算法RSA加密AES密鑰來實現高效的密鑰管理。利用Visio Studio 2017+Qt軟件開發(fā)測試界面,通過數據總線將算法寫入STM32單片機進行方案性能測試,優(yōu)選出最佳的運行模式,同時驗證了混合加解密方案的有效性。總結得到,方案的耗時長短取決于RSA算法的加解密或簽名驗簽的效率。

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.

非侵入式負荷監(jiān)測(Non-Intrusive Load Monitoring,NILM)裝置為裝載于智能電表的模塊,通過測量并分析電力入口處的功率、電壓、電流等電量信號,獲取系統內各用電負荷的運行狀態(tài)數據[1]。NILM裝置能準確統計和呈現出各用電設備的用電量及用電時間,幫助用戶改善用電習慣,節(jié)約用電,但缺乏可靠保護,極易被追蹤和攻擊,存在數據信息泄漏的風險[2]。國家密碼局常用的加密算法是SM系列加密算法,文獻[3]運用國密算法SM2與SM4加密武器裝備的數據,并驗證了可行性。國際上流行使用的加密算法較多,如DES、AES、RSA等,文獻[4]利用其中的DES與AES算法來保障網絡環(huán)境下安全通信和信息傳輸的安全。本文分析了NILM數據安全所面臨的風險,在國內外現有的密碼技術中尋找最佳的密碼技術加密方案。利用STM32單片機平臺進行方案測試和數據處理分析,最終驗證了方案的有效性和耗時長短。
