The main purpose is to realise that closed-loopsystems are stochastically stable with or without replay attacks. Firstly, the tampered sensorsunder replay attacks can be identified via the proposed detection method. Then, an asynchronousstatic output feedback controller is designed, which can eliminate the negative impactcaused by replay attacks in view of the detection results.

The main purpose is to realise that closed-loopsystems are stochastically stable with or without replay attacks.

Then, an asynchronousstatic output feedback controller is designed, which can eliminate the negative impactcaused by replay attacks in view of the detection results.

Finally, a numerical example and apractical example are given to verify the effectiveness and superiority of the proposed method.
