A usual concern against physical layer security is that the legitimate parties would need to have (partial) channel state information (CSI) of the eavesdropper in order to design t...
We investigate secure communications for a four-node relayeavesdropper channel with multiple data stream transmission, assuming that the eavesdropper’s channel state information...
—We study the optimum location of an eavesdropper from a secrecy capacity perspective in multiterminal networks with power control. We determine the logical location of an eavesd...
We study the security of communication between a single transmitter and multiple receivers in a broadcast channel in the presence of an eavesdropper. Characterizing the secrecy ca...
In this two-part paper, we consider the transmission of confidential data over wireless wiretap channels. The first part presents an information-theoretic problem formulation in w...
