網(wǎng)絡化控制系統(tǒng)虛假數(shù)據(jù)注入攻擊的設計與檢測摘要：隨著互聯(lián)網(wǎng)技術(shù)的不斷升級和應用場景的不斷擴大，網(wǎng)絡化控制系統(tǒng)已經(jīng)成為了現(xiàn)代工業(yè)生產(chǎn)中不可或缺的重要組成部分。然而，這些控制系統(tǒng)的安全受到很大的威脅，尤其是針對虛假數(shù)據(jù)注入攻擊的威脅。本文主要討論了網(wǎng)絡化控制系統(tǒng)虛假數(shù)據(jù)注入攻擊的設計與檢測。

首先，本文分析了網(wǎng)絡化控制系統(tǒng)的特點及其遇到的威脅，重點分析了虛假數(shù)據(jù)注入攻擊的原理及其危害。然后，針對虛假數(shù)據(jù)注入攻擊的特點，提出了一種基于不完整Nash均衡的攻擊模型，通過動態(tài)調(diào)整虛假數(shù)據(jù)的注入策略，實現(xiàn)對網(wǎng)絡化控制系統(tǒng)的攻擊。

接著，本文提出了一種檢測虛假數(shù)據(jù)注入攻擊的方法，該方法基于異常檢測和時間序列分析技術(shù)，可以實現(xiàn)對控制系統(tǒng)中異常數(shù)據(jù)的檢測和識別，并及時進行預警和處理。最后，通過模擬實驗驗證了本文所提出的虛假數(shù)據(jù)注入攻擊模型及其檢測方法的有效性和實用性。

關鍵詞：網(wǎng)絡化控制系統(tǒng)，虛假數(shù)據(jù)注入攻擊，不完整Nash均衡，異常檢測，時間序列分析
