Abstract: This paper provides a comprehensive review of the domain of physical layersecurity in multiuser wireless networks. The essential premise ofphysical-layer security is to enable the exchange of confidential messages overa wireless medium in the presence of unauthorized eavesdroppers without relyingon higher-layer encryption. This can be achieved primarily in two ways: withoutthe need for a secret key by intelligently designing transmit codingstrategies, or by exploiting the wireless communication medium to developsecret keys over public channels. The survey begins with an overview of thefoundations dating back to the pioneering work of Shannon and Wyner oninformation-theoretic security. We then describe the evolution of securetransmission strategies from point-to-point channels to multiple-antennasystems, followed by generalizations to multiuser broadcast, multiple-access,interference, and relay networks. Secret-key generation and establishmentprotocols based on physical layer mechanisms are subsequently covered.Approaches for secrecy based on channel coding design are then examined, alongwith a description of inter-disciplinary approaches based on game theory andstochastic geometry. The associated problem of physical-layer messageauthentication is also introduced briefly. The survey concludes withobservations on potential research directions in this area.
