On Random Coding Bound for E-capacity Region of the Broadcast Channel With Confidential Messages
Abstract
The information theoretic security recently has attracted much attention [8]. One of the important objects in the secure communication is the broadcast channel with confidential messages (BCC) first investigated by Csiszár and Körner [1]. The model is depicted in Fig.1. The BCC involves two discrete memoryless channels with two sources, one encoder and two receivers. A common message must be transmitted at rate R0 to both receivers and a private message to the intended receiver at rate R1 while keeping the other receiver ignorant of it with equivocation rate Re.
