<p>In the distributed security control for air-sea heterogeneous multiagent systems (HMASs) with cooperative-antagonistic interactions, data security and transient-steady state performance of the system are two key problems. To ensure data security, an intermittent privacy preservation (IPP) mechanism is proposed for the first time. A novel setting time initial mask function and a novel intermittent mask function are constructed. Users can implement intermittent preservation for the system according to actual requirements, which solves the irreversibility problem after conventional mask disappears and balances control accuracy and system security. To ensure transient-steady state performance, a novel error transformation function (ETF) is proposed and integrated into the predefined-time prescribed performance control strategy. Compared to conventional hyperbolic tangent type ETFs, the proposed ETF can improve the convergence accuracy of errors under the same conditions. Furthermore, a unified model of the air-sea HMASs is established, which improves the model accuracy compared with the simplified model. Finally, the proposed IPP security control strategy is applied to the air-sea delivery mission to verify its feasibility and effectiveness.</p>
