Adversarial End-to-End Communication System: Dual Mechanisms for Anti-Interference and Anti-Eavesdropping

Due to the broadcast characteristics of wireless channels, wireless communication systems not only encounter internal interference but also face the threat of eavesdropping. This paper proposes a multi-user symmetric encryption end-to-end (E2E) communication system that integrates both anti-interference and anti-jamming capabilities. Experimental results demonstrate that the proposed system is robust to changes in interference conditions, maintaining secure communication for all users with very minimal performance degradation. Specifically, with 2 users, a modulation order of 16, achieving a symbol error rate (SER) of 10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">−4</sup> requires only a 0.7 dB increase in the signal-to-noise ratio (SNR). In addition, the eavesdropper's SER is as high as 93.75%, which is equivalent to randomly guessing 16 symbols.
