A knapsack problem formulation for relay selection in secure cooperative wireless communication
—Cooperative jamming (CJ) schemes support secure wireless communication in the presence of one or more eavesdroppers. Larger numbers of cooperative relays provide better secrecy ...

Secure communications with insecure feedback: breaking the high-SNR ceiling
A multiple-antenna Gaussian wiretap channel in which the number of antennas at the source is not greater than that at the eavesdropper is considered. Without feedback, the secrecy...

Cooperation with an untrusted relay: a secrecy perspective
We consider the communication scenario where a source-destination pair wishes to keep the information secret from a relay node despite wanting to enlist its help. For this scenario...

A Secure Communication Game with a Relay Helping the Eavesdropper
—In this work a four terminal Gaussian network composed of a source, a destination, an eavesdropper and a jammer relay is studied. The jammer relay does not hear the source trans...

Cooperative Secret Communication with Artificial Noise in Symmetric Interference Channel
We consider the symmetric Gaussian interference channel where two users try to enhance their secrecy rates in a cooperative manner. Artificial noise is introduced along with useful...
