摘要

摘要: 為確保網絡控制系統中傳輸數據的完整性、實時性、機密性和可用性,提高系統對抗數據攻擊的能力,提出了一種基于MD5散列碼、時間戳和AES加密算法的數據安全傳輸策略,該策略兼顧了系統中控制器端和被控對象端數據傳輸的安全性和實時性.并從控制策略的角度出發,考慮在系統遭受到數據攻擊后,采用基于網絡回路時延的網絡預測控制方法對數據攻擊進行補償,使系統在受到一定強度的數據攻擊后仍然能夠進行穩定的控制,從而提高網絡控制系統應對攻擊的能力.采用S100-1實訓平臺管道壓力控制系統驗證了基于安全傳輸策略的網絡化預測控制系統有較好的安全性和抗數據攻擊能力.

Abstract: To ensure the integrity, real-time performance, confidentiality and usability of data transmission in networked control systems and improve the ability of the system against data attacks, a data transmission strategy based on the MD5 hash code, time stamp, and AES encryption algorithm was proposed. This strategy takes into account the security and real-time of data transmission of both the controlled object side and the controller side of the networked control system. And the networked predictive control based on round trip time delay was used to compensate for the effect on the system after it had been attacked by data, so that the system can be stably controlled after being attacked by some intensity of data and also achieves a better control effect, thereby improving the ability of network control systems to deal with attacks. The S100-1 training platform pipeline pressure control system is used to prove that the proposed networked predictive control system based on the secure transmission strategy has better security and anti-attack ability.
