The capacity of a time-varying block-memoryless channel in which the transmitter and the receiver have access to (possibly different) noisy causal channel side information (CSI) i...
Discrete-time Rayleigh fading single-input single-output (SISO) and multiple-input multipleoutput (MIMO) channels are considered, with no channel state information at the transmit...

Abstract. Assuming an insecure quantum channel and an authenticated classical channel, we propose an unconditionally secure scheme for encrypting classical messages under a shared ...
In this paper, we examine general mechanisms that a covert channel may exploit and derive new minimum requirements for setting up a covert channel. We also propose a new classifica...
