“…The novel protocol uses a four step procedure to ensure wireless information-theoretic security: (i) common randomness via opportunistic transmission; (ii) message reconciliation; (iii) common key generation via privacy amplification; and (iv) message protection with a secret key. The authors in [11] introduce an idea of using the abstraction of a virtual array of physical arrays to provide security against eavesdropping. They solve the problem that using smart antennas at higher layers for security with an intelligent consideration of MAC and security issues.…”

We consider a wireless information surveillance in UAV network, where a legitimate unmanned aerial vehicle (UAV) proactively eavesdrops communication between two suspiciousUAVs. However, challenges arise due to lossy airborne channels and limited power of the UAV. In this paper, we study an emerging legitimate eavesdropping paradigm that the legitimateUAV improves the eavesdropping performance via jamming the suspicious communication. Moreover, a power efficient legitimate eavesdropping scheme, PELE, is proposed to maximize the number of eavesdropped packets from the legitimate UAV while maintaining a target signal to interference plus noise ratio at the suspicious link. Numerical results are shown to validate the performance of PELE. Additionally, four typical fading channel models are applied to the network so as to investigate their impact on PELE.

“…In a typical indoor environment, a message sent to a legitimate user will be exposed to any potential eavesdropper who is within range. The principle of physical space security is to hide the knowledge of the existence of the message from the eavesdropper rather than encrypting the contents of the message from the eavesdropper [2], [3].…”
