Secrecy Gain: a Wiretap Lattice Code Design
Published 23 Apr 2010 in cs.IT, cs.CR, and math.IT | (1004.4075v2)
Abstract: We propose the notion of secrecy gain as a code design criterion for wiretap lattice codes to be used over an additive white Gaussian noise channel. Our analysis relies on the error probabilites of both the legitimate user and the eavesdropper. We focus on geometrical properties of lattices, described by their theta series, to characterize good wiretap codes.
