This paper proposes a solution to enhance the reliability and security of the data transmission channel between the Functional Testing Device and control modules of the aerial vehicle ground launch system under harsh operating conditions, where both intentional and random electromagnetic interference may occur. Based on the principles of game theory, the study models the problem of optimizing encryption parameters and feedback mechanisms as an adversarial interaction between the communication system and the interference source. The objective is to maximize the guaranteed data transmission rate under an average interference power constraint. An optimization algorithm is proposed to select the most suitable set of parameters (code block length, error correction capability, and signal basis) adapted to the specific characteristics of command and status data in the missile system. Simulation results demonstrate that the proposed solution significantly improves anti-jamming capability compared to conventional methods, thereby enhancing readiness and safety in the missile launch preparation and firing process.
