Well-Rounded Lattices: Towards Optimal Coset Codes for Gaussian and Fading Wiretap Channels
Well-Rounded Lattices: Towards Optimal Coset Codes for Gaussian and Fading Wiretap Channels
The design of lattice coset codes for wiretap channels is considered. Bounds on the eavesdropper's correct decoding probability and information leakage are first revisited. From these bounds, it is explicit that both the information leakage and error probability are controlled by the average flatness factor of the eavesdropper's lattice, which …
