Abstract: Physical layer security has recently emerged as a promising technique to realize secret transmissions. The key idea of such secret schemes is to exploit the dynamic nature of wireless channels and explore the possibility of achieving perfect secrecy data transmissions. Existing works for physical layer security have demonstrated that non-zero secrecy rates can be achieved when the legitimate transceiver has a better channel condition than the eavesdropper. However, in most communication systems, end users have specific requirements for the quality of service. Therefore it is necessary to design spectrally efficient secure transmission protocols and meet the predefined quality of service, which has been received a lot of attention recently. In this talk, several physical layer security transmission protocols will be introduced for various communication scenarios with different assumptions about channel state information.

Bio: Dr. Zhiguo Ding received his B.Eng in Electrical Engineering from the Beijing University of Posts and Telecommunications in 2000, and the Ph.D degree in Electrical Engineering from Imperial College London in 2005. From 2005 to 2010, he had been with Queen’s University Belfast, Imperial College and Lancaster University. Since June 2010, he has been with School of Electrical, Electronic, and Computer Engineering, Newcastle University, currently as a Reader. Currently he is working in Professor Vincent Poor’s group at Princeton University as a visiting researcher, supported by FP7 Marie Curie Fellowship. His research interests include energy harvesting networks, physical layer security, MIMO and cooperative networks.
