The strong secrecy transmission problem of the arbitrarily varying wiretap channel (AVWC)
with input and state constraints is investigated in this paper. First, a stochastic-encoder code …

We study the arbitrarily varying channel (AVC) with input and state constraints, when the
encoder has state information in a causal or noncausal manner. For the causal state …

In this work, we study the arbitrarily varying broadcast channel (AVBC), when state
information is available at the transmitter in a causal manner. We establish inner and outer …

We establish the deterministic-code capacity region of a network with one transmitter and
two receivers: an ordinary receiver and a robust receiver. The channel to the ordinary …

Secure communication in a potentially hostile environment is becoming more and more
critical. The A rbitrarily V arying W iretap C hannel (AVWC) provides information-theoretical …

We study the arbitrarily varying relay channel, which models communication with relaying in
the presence of an active adversary. We establish the cutset bound and partial decode …

We study the arbitrarily varying channel (AVC) with input and state constraints, when the
encoder has state information in a causal manner. Lower and upper bounds on the random …

The open nature of the wireless communication medium makes it inherently vulnerable to an
active attack, wherein a malicious adversary (or jammer) transmits into the medium to disrupt …

To study the fundamental limits on the joint transmission of data of different levels of
sensitivity, we establish the deterministic-code capacity region of a network with one …

This thesis is comprised of two parts. Both parts study information-theoretic aspects of joint
transmission of data of different levels of sensitivity. The more sensitive data is better …
