Outline of Research at the Start

Integrated satellite-aerial-terrestrial (ISAT) network serves as the fundamental architecture for future B5G/6G networks, while the covert wireless communication (CWC) is a critical secure communication paradigm. The goal of this project is to conduct a complete study on the CWC in ISAT network built upon the promising physical layer security (PLS) technologies by investigating its three fundamental issues, namely the PLS-based CWC scheme design for ISAT, CWC performance modeling, and CWC performance enhancement/optimization.

Outline of Annual Research Achievements

1. We studied the covert communications in MIMO systems, two-hop relay systems, distributed networks with multiple non-orthogonal multiple access (NOMA) systems, and relay-assisted device-to-device (D2D) networks. The related transmission/ forwarding mode selection and covert rate maximization issues were investigated as well.
2. We developed a solid theoretical framework to analyze the practically achievable covert communication performance in a two-hop relay system under CSI estimation error and feedback delay, and explored the joint optimization of channel inversion power and data symbol length to maximize covert rate under such imperfect CSI.
3. We investigated the covert communications in UAV-enabled wireless communication systems, and explored the applications of THz communications and multicast transmissions in supporting covert communications in such systems.
4. We explored the covert communication in satellite-terrestrial systems, developed corresponding joint beamforming and jamming (JBJ) scheme, and studied the joint optimal design of beamforming, jamming and satellite antenna boresight for covert rate maximization.
5. We also explored the related physical layer authentication (PLA) problem for covert communications, and proposed a PLA scheme for MmWave MIMO wireless Systems based on fine-grained channel/hardware features, as well as a tag-based PLA scheme for RIS-assisted wireless systems.

2: Research has progressed on the whole more than it was originally planned.

Reason

For terrestrial systems, we studied the covert communications in MIMO systems, two-hop relay systems, distributed networks with multiple NOMA systems, and relay-assisted device-to-device (D2D) networks. We also developed a solid theoretical framework to analyze the practically achievable covert communication performance in a two-hop relay system under CSI estimation error and feedback delay. For UAV-enabled wireless communication systems, we explored the applications of THz communications and multicast transmissions in supporting covert communications in such systems. For satellite-terrestrial systems, we developed corresponding joint beamforming and jamming (JBJ) scheme for covert communications, and studied the joint optimal design of beamforming, jamming and satellite antenna boresight for covert rate maximization. We also explored the related physical layer authentication (PLA) problem for covert communications in MmWave MIMO wireless Systems and RIS-assisted wireless systems. Four journal papers have been submitted and another four journal papers are now under preparation.

Strategy for Future Research Activity

Covert rate (CR), detection-probability (DP) and delay serve as the three fundamental performance metrics for CWC. We will develop theoretical frameworks for CR/DP/delay modeling in TT scenario under more practical channel/warden/detection models, derive delay/DP-constrained CR and investigate the related performance tradeoffs among CR/DP/delay. With help of these works, we will further develop theoretical frameworks for CR/DP/delay modeling for both AT and SAT scenarios, in which the effects of UAV mobility, satellite orbit/mobility and more practical channel/warden/detection models will be jointly considered. In particular, we will establish a general theoretical framework for CWC performance modeling in the ISAT networks.
We will explore the joint designs of different PLS techniques for the enhancement of CWC performance in the TT scenario under more practical channel/warden/detection models. Based on these works, we will then examine the CWC performance enhancement in AT and SAT scenarios by jointly exploiting these PLS technologies, UAV location/mobility and satellite orbit/mobility. Notice that power control is a crucial issue that can significantly affect the CWC performance, we will further explore the CWC performance optimization with the consideration of power constraint, for which a general Successive Convex Approximation-based optimization framework and iterative searching algorithms will be developed.
