Abstract: This article focuses on the pinning synchronization issue for Takagi–Sugeno (T–S) fuzzy complex dynamical networks (CDNs) under critical-data-targeted denial-of-service (DoS) attacks. Firstly, a novel critical-data-targeted DoS attack method is considered for the attacker to enhance the destructiveness of the attack against various nodes. Contrasting with most existing DoS attack models, this attack scheme can selectively attack critical data, allowing the attacker to cause relatively large damage to system performance. Secondly, we establish a new pinning synchronization control model for T–S fuzzy CDNs with random coupling delays. It can describe the actual world more accurately compared with the general model of CDNs. And the issue of asynchronous premise variables is solved. Furthermore, a new secure synchronization criterion is presented by leveraging the appropriate Lyapunov–Krasovskii function to realize the H∞ performance of the system against critical-data-targeted DoS attacks. Finally, three examples are offered to confirm the efficacy of the suggested results.
