Abstract

A four-receiver degraded broadcast channel with secrecy outside a bounded range is studied, over which a transmitter sends four messages to four receivers. In the model considered, the channel quality gradually degrades from receiver 4 to receiver 1, and receiver k is required to decode the first k messages for k = 1,⋯, 4. Furthermore, message 3 is required to be secured from receiver 1, and message 4 is required to be secured from receivers 1 and 2. The secrecy capacity region is established. The achievable scheme includes not only superposition, binning and embedded coding used in previous studies, but also rate splitting and sharing particularly designed for this model, which is shown to be critical to further enlarge the achievable region and enable the development of the converse proof.
