Abstract :
Rate distortion theory is considered for the Shannon cipher system (SCS). The admissible region of cryptogram rate R, key rate Rk, legitimate receiver´s distortion D, and wiretapper´s uncertainty h is determined for the SCS with a noisy channel. Furthermore, inner and outer bounds of the admissible region of R, Rk, D, and wiretapper´s attainable minimum distortion D˜ are derived for the SCS with a finite discrete source and a noiseless channel
