Wiretap Channel With Side Information

Abstract

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> This correspondence gives an achievable rate equivocation region for the discrete memoryless wiretap channel with side information. We extend our results to the Gaussian case. The main contribution of this correspondence is that, for the Gaussian wiretap channel, the side information helps to get a larger <emphasis emphasistype="boldital">secrecy capacity</emphasis> and a larger <emphasis emphasistype="boldital">rate equivocation</emphasis> region. </para>
