Abstract: Recent information-theoretic results on a class of broadcast channels with layered decoding and/or layered secrecy are reviewed. In this class of models, a transmitter sends multiple messages to a set of legitimate receivers in the presence of a set of eavesdroppers, whose channels can be ordered based on the quality of received signals. Receivers with better channel quality are required to decode more messages, and eavesdroppers with worse channel quality are required to be kept ignorant of more messages. The design of achievable schemes and the characterization of the corresponding secrecy capacity regions are presented. Comparison of the designs for different models is discussed. Applications of these information-theoretic models to the study of secure communication over fading wiretap channels and secret sharing are also presented to illustrate potential applications of these models.
