Recently, Dr. Tian Wen, the Key Laboratory of Intelligent Security Technology in Complex Environment of the Ministry of Education of our College, published an article in IEEE Transactions on Wireless Communications (SCI Area 1, Three High T1 journal, Impact factor 8.2) was published titled "UAV-Enabled Communication Strategy against Detection in Covert Communication With Asymmetric Information "Paper (IEEE TWC, 2024, https://doi.org/10.1109/TWC.2023.3336278), NUIST for the first unit, Dr Tian Wen as the first author.

In order to effectively improve the rate of UAV-assisted wireless covert communication, this paper proposed an asymmetric information game model for UAV-assisted covert communication. Specifically, the model focuses on the covert communication countermeasure process based on information asymmetry, introduces the UAV into the covert communication relay to assist the communicator and the jammer respectively, analyzes the interaction between the two sides of the covert communication countermeasure, and deduces the optimal strategy of both sides. At the same time, the existence condition of the Bayesian Nash equilibrium in the proposed model is further proved. This research work also provides a research idea for the implementation of tactical tactics in actual communication confrontation.
