Recently, Dr. Tian Wen from the Key Laboratory of Intelligent Guarantee Technology for Complex Environments of our college published a paper titled "UAV-Enabled Communication Strategy against Detection in Covert Communication With Asymmetric Information" in "IEEE Transactions on Wireless Communications" (SCI Zone 1, high-quality T1 journal, impact factor 8.2) (IEEE TWC, 2024, https://doi.org/10.1109/TWC.2023.3336278). Nanjing University of Information Science & Technology is the first unit, and Dr. Tian Wen is the first author.

This research proposes a UAV-assisted covert communication asymmetric information game model to effectively improve the rate of UAV-assisted wireless covert communication. Specifically, this model focuses on the covert communication confrontation process based on asymmetric information. UAVs are introduced into the covert communication relay to assist the communicating party and the jamming party respectively, analyzing the interaction between the two parties in wireless covert communication confrontation, and deriving the optimal strategies of both parties. At the same time, the existence conditions of Bayesian Nash equilibrium in the proposed model are further proved. This research work also provides research ideas for the implementation of tactics and methods in actual communication confrontation.
