This article discusses the consensus problem of the discrete-time multiagent system (MAS) by event-triggered secure control in infinite time domain against complex cooperative attacks, which consists of false data injection attacks (FDIAs) and replay attacks (RAs). Due to the openness of the network, attackers attempt to destroy the consensus by damaging the integrity of the measured signal in the information transmission channel. A novel complex cooperative attacks model is first built. FDIA and RA, which appear randomly on the data communication channel from sensor to controller, are modeled in a unified framework through Bernoulli process. The state-dependent event-triggered control scheme (ETCS), which reduce the demand for network bandwidth, is adopted to update control signals. This article is to design an appropriate ETCS to make MAS reach consensus under FDIA and RA. The sufficient conditions are derived to ensure the event-triggered consensus and consensus with guaranteed position performance by using the stochastic analysis method. Finally, the simulation results show the feasibility of the proposed ETCS.
