Interference engineering for heterogeneous wireless networks with secrecy

Wireless secrecy is essential for information superiority, communication confidentiality, and economic advantage in modern information society. Contemporary security systems are based on cryptographic primitives and can be complemented by techniques that exploit the intrinsic properties of the wireless environment. We present foundations for design and analysis of heterogeneous wireless networks with intrinsic secrecy provided by node spatial distribution, wireless propagation medium, and aggregate network interference. Guided by our preliminary results, we envision that network interference can be engineered to provide beneficial effects to network secrecy opening to new perspectives for the coexistence of heterogeneous networks.
