A Probability-Aware AI Framework for Reliable Anti-Jamming Communication

Abstract

Adversarial jamming attacks have increased on communication systems, causing distortion and threatening transmissions. Typical attacks rely on traditional, well-defined cryptographic protocols and frequency-hopping techniques. Nevertheless, these techniques become vulnerable when facing intelligent jammers. To address this issue, we introduce a new framework that integrates Siamese neural networks with a dual-probability-attention mechanism (DPAM) to provide reliable anti-jamming communication and robust protection. This framework contains several components, which are (1) twin neural networks to execute coordinated cryptographic adaptation operation using a contrastive learning approach, (2) a DPAM module to analyse signals using probability encoding and dual temporal-spectral attention to enhance accurate recognition, (3) adversarial training to counter growing attack patterns and (4) a lightweight neural encryption module that is developed to provide real-time operation. Internal DPAM architecture combines probability distributions with Bayesian attention fusion. This combination increases the detection by 23% when compared to other attention mechanisms. Conducted simulation evaluations on a public dataset shows that the frameworks reached an accuracy of 98.7%, whereas other reinforcement learning (RL) methods achieved 82%. In addition, 45% reduction in latency was reached when compared to frequency-hopping solutions. Furthermore, the solution got up to 96% resilience against attacks.
