Two-Hop Secure Communication Using an Untrusted Relay: A Case for Cooperative Jamming
—We consider a source-destination pair that can communicate only through an unauthenticated intermediate relay node. In this two-hop communication scenario, where the cooperation...

Secure transmission with multiple antennas I: the MISOME wiretap channel
Abstract--The role of multiple antennas for secure communication is investigated within the framework of Wyner's wiretap channel. We characterize the secrecy capacity in terms...

The Capacity Region of a Class of Discrete Degraded Interference Channels
We provide a single-letter characterization for the capacity region of a class of discrete degraded interference channels (DDICs). The class of DDICs considered includes the discre...

On broadcast channels with binary inputs and symmetric outputs
We study the capacity regions of broadcast channels with binary inputs and symmetric outputs. We study the partial order induced by the more capable ordering of broadcast channels...
