Private Broadcasting over Independent Parallel Channels
Ashish Khisti, Tie Liu
We study private broadcasting of two messages to two groups of receivers over independent parallel channels. One group consists of an arbitrary number of receivers interested in a…
Artificial-Noise Alignment for Secure Multicast using Multiple Antennas
Ashish Khist, Dongye Zhang
We propose an artificial-noise alignment scheme for multicasting a common-confidential message to a group of receivers. Our scheme transmits a superposition of information and nois…
Secret-Key Agreement Capacity over Reciprocal Fading Channels: A Separation Approach
Ashish Khisti
Fundamental limits of secret-key agreement over reciprocal wireless channels are investigated. We consider a two-way block-fading channel where the channel gains in the forward and…
Streaming Codes for Channels with Burst and Isolated Erasures
Ahmed Badr, Ashish Khisti, Wai-Tian Tan +1
We study low-delay error correction codes for streaming recovery over a class of packet-erasure channels that introduce both burst-erasures and isolated erasures. We propose a simp…
On Modulo-Sum Computation over an Erasure Multiple Access Channel
Ashish Khisti, Brett Hern, Krishna Narayanan
We study computation of a modulo-sum of two binary source sequences over a two-user erasure multiple access channel. The channel is modeled as a binary-input, erasure multiple acce…
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…
