Outline of Final Research Achievements

By exploiting the inherent physical layer characteristics of wireless communication channels, we proposed several physical layer security schemes to secure the IoT wireless communications in the 5G era, including mobile ad hoc networks and millimeter-wave communication systems. We also developed theoretical frameworks to analyze the security performances of the proposed schemes. Our proposed security schemes enhance the security level achieved by the traditional cryptographic security approaches and serve as promising candidates for securing IoT wireless communications in the 5G era.
