Lattices for the Gaussian Wiretap Channel
(A common work with Frédérique Oggier and Patrick Solé)
We use the lattice coset construction with Λe being the coarse lattice and Λb being the fine lattice. Data bits label the cosets of Λe/Λb while pseudo-random bits label points in Λe. We have found a new lattice invariant called "Secrecy Gain" that characterizes the behavior of Λe in terms of physical security. Two conference papers have been published until now,
