Capacity region of non-degraded wiretap channel with noiseless feedback

摘要

The non-degraded wiretap channel with noiseless feedback is first investigated by R. Ahlswede and N. Cai, where lower and upper bounds on the secrecy capacity are provided in their work. However, the capacity-equivocation region has not been determined yet. In this paper, the capacity-equivocation region is determined for the non-degraded wiretap channel with noiseless feedback. Furthermore, the secrecy capacity of this model is formulated, which provides the best transmission rate with perfect secrecy.
