Query: Finite State Markov Wiretap Channel with Delayed Feedback   The finite state Markov channel (FSMC), where the channel transition
probability is controlled by a state undergoing a Markov process, is a useful
model for the mobile wireless communication channel. In this paper, we
investigate the security issue in the mobile wireless communication systems by
considering the FSMC with an eavesdropper, which we call the finite state
Markov wiretap channel (FSM-WC). We assume that the state is perfectly known by
the legitimate receiver and the eavesdropper, and through a noiseless feedback
channel, the legitimate receiver sends his received channel output and the
state back to the transmitter after some time delay. Inner and outer bounds on
the capacity-equivocation regions of the FSM-WC with delayed state feedback and
with or without delayed channel output feedback are provided in this paper, and
we show that these bounds meet if the eavesdropper's received symbol is a
degraded version of the legitimate receiver's. The above results are further
explained via degraded Gaussian and Gaussian fading examples.
