内容提要（Outline of the Talk）:

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.
