Secure Power Regulation Under Jamming: A Nonlinear Stability Perspective for 5G/6G Networks

Abstract Security threats in 5G and emerging 6G networks increasingly arise from physical-layer vulnerabilities, where adversarial actions such as jamming, spoofing, and interference injection directly affect the nonlinear dynamics of power control and resource allocation mechanisms. These malicious disturbances act as structured perturbations that may disrupt network stability, degrade quality-of-service, or force system divergence. This paper develops a Lyapunov-based stability framework for analyzing and mitigating the impact of adversarial perturbations in nonlinear wireless communication systems. A new nonlinear secure power-update model is introduced, incorporating both unintentional disturbances and intentional jamming signals as bounded or energy-constrained perturbations. Sufficient conditions for practical secure stability are derived, ensuring that the system state remains bounded despite adversarial influence. Novel performance metrics based on energy evolution, attack resilience, and convergence distortion are proposed. Numerical simulations demonstrate the behavior of the secure control system under various jamming intensities, showing how Lyapunov-guided countermeasures can stabilize the network, maintain confidentiality at the physical layer, and mitigate the degradation of SINR and power trajectories. The results provide a rigorous mathematical foundation for designing robust, security-aware control algorithms in next-generation 5G/6G infrastructures.
