This article investigates the FlexRay (FR) protocol-based dynamic event-triggered (DET) secure filtering problem with the high-rate communication (HRC) network for the interval type-2 (IT-2) fuzzy networked system. For fear of data collisions and preempting limited communication resources, a novel DET-FR (DETFR) protocol is adopted to schedule sensor nodes. Different sensors are employed for distinct protocols and data-holding strategies to reinforce the efficiency of network transmission. Moreover, considering the random occurrence of cyber attacks and fading measurements in the HRC channel, the attack parameters are represented by the Bernoulli process, and measurement attenuation coefficients are expressed by the random variables of equidistribution on a fixed interval. Based on this, to ensure that the error dynamics meet the disturbance attenuation level, several sufficient conditions are given. Subsequently, the DETFR protocol-based secure filtering algorithm is developed to acquire the fuzzy filter parameters. Eventually, the validity of our designed secure filtering algorithm is proved through two examples.
