This paper addresses the secure bipartite consensus control problem for multi-agent systems under denial-of-service (DoS) attacks. A class of aperiodic time-sequence-based DoS attacks is considered, and its impact on both undirected and directed network topologies is analyzed. The stability analysis is conducted using a Lyapunov function approach combined with an iterative method. To reduce energy consumption and prevent Zeno behavior, a hybrid dynamic event-triggered mechanism is introduced. This mechanism incorporates an improved dynamic event-triggering condition, which determines when each agent updates its control signal and transmits its currently triggered state to neighboring agents. The proposed approach integrates this mechanism with the developed distributed control protocol and to ensure bipartite consensus even in the presence of DoS attacks. The effectiveness of the method is demonstrated through two simulation examples.
