| Abstract: | To meet the anti-tamper requirement for control software, a new method is proposed to construct the moving target defense system of control software based on multi-variant and virtualization. The function of active defense and security situational awareness is achieved by heterogeneous redundancy, Dynamic reconfiguration and multimode voting of variant. multi-variant execution environment is structured by virtualization. The technical route, system architecture, dynamic reconfiguration, voting algorithm and synchronization mechanism are detailed in this paper. The research results show that this technique can improve the reliability and security actively for industrial control systems. |
