Potential　malicious　attacks　have　been　a　significant　security　concern　for　network　system　applications.　However,　there　are　few　studies　on　filtering　for　hybrid　network　attacks　in　switching　systems.　This　paper　considers　a　Kalman　filtering　problem　for　the　switched　systems　that　suffer　from　deception　attacks　and　denial-of-service　attacks.　A　new　network　transmission　model　for　switching　systems　is　established.　Then,　based　on　the　minimum　mean　square　error　criterion,　a　Kalman　filter　with　low　conservatism　is　designed　for　the　discrete-time　switched　system.　The　newly　switched　Kalman　gain　matrix　is　deduced　including　the　random　variation　of　the　switching　signal　after　being　attacked　by　the　network.　Finally,　the　effectiveness　of　the　proposed　filter　is　verified　by　the　numerical　simulation.　©　2023　IEEE.
