MIMO Broadcast Channel with an Unknown Eavesdropper: Secrecy Degrees of Freedom
Xiang He, Ashish Khisti, Aylin Yener
We study a multi-antenna broadcast channel with two legitimate receivers and an external eavesdropper. We assume that the channel matrix of the eavesdropper is unknown to the legit…
MIMO Multiple Access Channel with an Arbitrarily Varying Eavesdropper
Xiang He, Ashish Khisti, Aylin Yener
A two-transmitter Gaussian multiple access wiretap channel with multiple antennas at each of the nodes is investigated. The channel matrices at the legitimate terminals are fixed a…
MIMO Wiretap Channels with Arbitrarily Varying Eavesdropper Channel States
Xiang He, Aylin Yener
In this work, a class of information theoretic secrecy problems is addressed where the eavesdropper channel states are completely unknown to the legitimate parties. In particular,…
The Gaussian Many-to-1 Interference Channel with Confidential Messages
Xiang He, Aylin Yener
The many-to-one interference channel has received interest by virtue of embodying the essence of an interference network while being more tractable than the general K-user interfer…
Strong Secrecy and Reliable Byzantine Detection in the Presence of an Untrusted Relay
Xiang He, Aylin Yener
We consider a Gaussian two-hop network where the source and the destination can communicate only via a relay node who is both an eavesdropper and a Byzantine adversary. Both the so…
The Role of Feedback in Two-way Secure Communications
Xiang He, Aylin Yener
Most practical communication links are bi-directional. In these models, since the source node also receives signals, its encoder has the option of computing its output based on the…
