报告摘要:With the rapid advancement of communication and networking technologies, ubiquitous wireless network access and Internet
of Things (IoT) have become reality. Due to the "open air" nature of the wireless medium, the resource constraints of the wireless
devices, and distributed nature of wireless networks, ensuring wireless network security faces great challenges. Although
traditional cryptography-based mechanisms are widely used for securing wireless networks, there has been an increasing interest inproviding or enhancing wireless network security by exploiting various physical layer properties. Different from traditional computationalsecurity mechanisms, physical layer security is based on the physical principles of wireless channels and devices, thus provides a fundamentally different approach to secure wireless networks and provides another means of protection at the
physical layer. It can be widely applied in various wireless networks for providing different security services. It has a great
potential to simplify or avoid complex cryptographic computation and achieve information-theoretical security. This talk provides an overview of various techniques for securing wireless networks by exploiting
physical layer properties. Our recent works on extracting shared secret keys from wireless channels and physical layer
challenge-response authentication in wireless networks will be presented. Future directions in the physical layer security area and its applications will also be discussed.
