Physical Layer Security
Summary
Security of a wireless communication link has always been of great importance. In conventional wireless networks, security issues are primarily considered above the physical layer and are usually based on cryptographic methods. However, the broadcast nature of the wireless transmission medium makes eavesdropping extremely easy, and anyone within communication range can receive and possibly decode private transmission signals. Alternatively, physical layer based security explores the characteristics of the wireless channel to improve wireless transmission security. By utilizing physical layer security, it is possible to design a decentralized system that makes it impossible for malicious eavesdropper nodes to successfully decode a transmission stream. The key idea behind physical layer security is to exploit the physical characteristics of the wireless channel to provide secure communications.
