Securing Large-Scale D2D Networks Using Covert Communication and Friendly Jamming
Securing Large-Scale D2D Networks Using Covert Communication and Friendly Jamming
We exploit both covert communication and friendly jamming to propose a friendly jamming-assisted covert communication and use it to doubly secure a large-scale device-to-device (D2D) network against eavesdroppers (i.e., wardens). The D2D transmitters defend against the wardens by: 1) hiding their transmissions with enhanced covert communication, and 2) leveraging friendly …
