报告内容:Physical Layer Security
报告人:Prof. Ning Zhang, Texas A&M University-Corpus Christi

摘要:Security is a significant issue in wireless communication systems due to the openness of wireless medium. Traditionally, security is dealt with using upper layer cryptography schemes. However, the cryptography schemes might be broken due to the ever-increasing capabilities of attackers. An supplementary approach to enhance security is through physical layer, which can provide perfect security. In this talk, we will talk about the main idea about physical layer security through cooperation. We mainly focus on the following issues: i) with whom to cooperate; ii) how to stimulate cooperation; and iii) how to cooperate. A three-step cooperative scheme is proposed, whereby the source selects partners and stimulates them for secure communications by paying an amount of reward. Simulation results are provided to evaluate the proposed approach. Finally,  the potential research topics will be discussed.
