Combining artificial noise beam forming and concatenated coding schemes to effectively secure wireless communications

In this paper we present a new scheme combining artificial noise beam forming and secrecy coding to strengthen the security of existing wireless communication systems. Artificial noise and beam forming guarantee a radio advantage to legitimate users, enabling the use of our secrecy coding scheme to provide reliability and secrecy. This overall security protocol is compliant with existing widespread radio access technologies and it can be considered as a key-free add-on to improve security of the physical layer of wireless networks.
