This　article　investigates　the　secure　consensus　problem　of　general　linear　multiagent　systems　with　denial-of-service　(DoS)　attacks.　Owning　to　the　existence　of　DoS　attacks,　it　is　challenging　to　investigate　the　event-triggered　control　of　multiagent　systems　in　a　fully　distributed　manner.　This　article　presents　a　novel　dynamic　event-triggered　mechanism　to　alleviate　the　limited　communication　resources.　Moreover,　the　designed　mechanism　is　fully　distributed　and　scalable　owing　to　the　introduction　of　some　adaptive　coupling　weights.　Since　the　DoS　attacks　have　been　considered　in　the　event-triggered　rule　design,　a　novel　adaptive　parameter　with　an　additional　exponential　term　is　adopted　to　deal　with　DoS　attacks.　The　Lyapunov　design　also　introduces　such　a　term　for　the　subsequent　stability　analysis.　Sufficient　conditions　guaranteeing　the　asymptotic　consensus　of　the　studied　system　are　developed　in　light　of　the　controller＇s　parameters,　duration,　and　frequency　of　the　DoS　attacks.　Strict　proof　is　provided　to　demonstrate　that　a　secure　consensus　can　be　reached　effectively　under　the　proposed　control　mechanism.　Furthermore,　it　is　shown　that　the　Zeno　behavior　can　be　excluded　from　the　designed　triggering　mechanism.　Finally,　simulations　on　a　multiagent　system　consisting　of　interconnected　unmanned　intelligent　vehicles　are　conducted　to　verify　the　results.
