Codes for wireless wiretap channels

In this presentation we are interested in coding for wiretap wireless channels. First part is devoted to design criteria, second part will deal with the codes themselves. Nested lattices are the main ingredients to be used. We start with the Gaussian wiretap channel where it is shown that theta series have to be minimized. Then we give some ideas in the case of fading wiretap channels. In part two, we give some results that help finding good lattice codes of moderate and high length. Part of this work was supported by FP7 project PHYLAWS (EU FP7-ICT 317562).
