Achieving Physical-Layer Security in Programmable Wireless Networks
Achieving Physical-Layer Security in Programmable Wireless Networks
The broadcasting nature of wireless networks makes exposure to eavesdroppers a realistic threat. Physical Layer Security (PLS) has been widely recognized as a complementary and sometimes alternative approach to encryption. Several techniques have been proposed in the literature to implement PLS at the link-level. But so far, these techniques remain limited to the information theory domain, without practical implementations. In this talk, the speaker will demonstrate that PLS can be actually realized by tackling the problem at the network-level instead of the link-level, using a combination of Software-Defined Networking (SDN) and programmable wireless networking. This subsequently leads to a plethora of new opportunities in securing wireless networks, including secrecy optimization by network-endemic Friendly Jamming, and automated peer-to-peer trading of network performance against security.
