Some New Results on the Wiretap Channel with Causal Side Information

摘要

In this paper,the model of wiretap channel has been reconsidered for the case that the main channel is controlled by channel state information (side information),and it is available at the transmitter in a causal manner.Inner and outer bounds are derived on the capacity-equivocation region for this new model,and the secrecy capacity is described and bounded,which provides the best transmission rate with perfect secrecy.
