| 研究実績の概要 |
1.We proposed a novel secure wireless communication paradigm where the physical layer security technology is applied to counteract both detection and eavesdropping attacks.
2. We proposed two relay selection schemes for covert communication in networks with multiple relays and fading channels, and developed a Bayesian Stackelberg framework to find the optimal mixed strategy for covert communication.
3. We explored the fundamental issues of the full-duplex and half-duplex relaying modes for achieving covert communication in wireless networks, and explored the multi-antenna covert communications in random wireless networks under warden collusion.
4. We proposed a secrecy guard zone based covert communication protocol for MANETs.
5. By exploiting the location-specific channel gain and transmitter specific phase noise, we propose a new PHY-layer authentication scheme for massive multiple-input multiple-output (MIMO) systems.

理由
We proposed a novel secure wireless communication paradigm to counteract both detection and eavesdropping attacks, and developed two relay selection schemes for covert communication in networks with multiple relays and fading channels. We explored the application of game theory on covert communication and developed a Bayesian Stackelberg framework to find the optimal mixed strategy for a covert communication system. We explored the fundamental issues of the full-duplex and half-duplex relaying modes for achieving covert communication, and explored the multi-antenna covert communications in random wireless networks under warden collusion. We proposed a secrecy guard zone based covert protocol in MANETs. By exploiting location-specific channel gain and transmitter-specific phase noise, we proposed a physical layer authentication scheme for covert communications in MIMO systems. By now, 6 journal papers have been published, and 7 papers have been submitted to top journals.

| 今後の研究の推進方策 |
Based on cooperative jamming, secure routing, link/relay selection and artificial noise, we will explore the joint designs of these security techniques for the enhancement of secrecy capacity (SC) of covert wireless communication (CWC). Notice that power control is a crucial issue that can significantly affect the CWC SC. With the help of our frameworks for CWC SC study and also our capacity optimization frameworks for MANETs, we will further explore the CWC SC optimization with the consideration of power constraint. We will disseminate our research results via publications in top journals and international conferences
