Abstract:

 

The problem of information theoretic security recently has attracted great attention. One of the problems concerns secure communication over a wiretap channel. The aim in the general wiretap channel model is to maximize the rate of the reliable communication from the source to the legitimate receiver, while keeping the confidential information as secret as possible from the eavesdroper (wiretapper). We introduce and investigate the E-capacity-equivocation region for the wiretap channel, which is the generalization of the capacity-equivocation region studied by Csisz\’ar and K\”orner. It is the closure of the set of all achievable rate-reliability and equivocation pairs, where the rate-reliability function presents optimal dependence of rate from error probability exponent (reliability). Previously the outer bound of this region was obtained. Here the inner bound of that region is constructed.
