Abstract
This paper shows that structured transmission schemes are a good choice for secret communication over interference networks with an eavesdropper. Structured transmission is shown to exploit channel asymmetries and thus perform better than randomly generated codebooks for such channels. For a class of interference channels, we show that an equivocation sum-rate that is within two bits of the maximum possible legitimate communication sum-rate is achievable using lattice codes.
