Abstract :
The coding theorem is proved for the system with two noisy channels, each of which is a broadcast channel. It is assumed that the legitimate channel is less noisy than the wiretapped channel. The admissible region of rates and security levels is obtained completely. The relationship of the present results to previous results is examined
