Abstract :
In this paper, we present an iterative algorithm for computing the secrecy capacity of broadcast channel with confidential message (BCC) in the situation that the main channel is less noisy than the eavesdropper´s channel. The global convergence of the algorithm is proved, and an expression for its convergence rate is derived.
