Securing communications is a challenging task. A ?rst attempt at security involves learning basic cryptography, and applying encryption algorithms to make messages unintelligible to adversaries. However, rarely is the task of securing a message - changesosimple.Whenonestepsbackandcontemplateshowtosecuretheexchange of communications, one realizes that the challenge is fundamentally one of bui- ing a complete solution. For example, one must ensure that all entities involved have proper and authenticated cryptographic material, or one must ensure that one veri?ably knows to whom one is communicating, or one must understand how the communication process takes place so as to make certain there are no vulnerabilities introduced by the communication process itself. Thislastissue, namelythatsecuritymethodsareoftenbuiltwithoutconsideration to how communication takes place, represents a fundamental gap where much of modern security research has fallen short.The security literature is ?lled with a mass of articles on cryptographic primitives and, although there are still many theoretical hurdlestobeovercomebythecryptographiccommunity,mostoftheseshortcomings areacademicandtherearenownumeroustextbooksoncryptographythatcanprovide thebasicintroductionneededtoemploycryptographicprimitives.Ontheothersideof thecoin,thesecurityliteratureisalso?lledwithamassofarticlesdevotedtobuilding secure protocols and, similarly, there are now numerous textbooks on computer securitythatprovidetheinstructionneededtodesignsecureprotocols.Unfortunately, the issue of how communication takes place or, more speci?cally, whether there are any speci?c issues that might arise or be circumvented because message exchanges aretakingplaceononemediumversusanother(e.g., wirelesscommunicationversus wired communication), is generally neglected.
A collection of high-impact research results in the area of physical layer security will serve as a valuable compendium to any researcher interested in conducting research in physical layer security
The book will be broken down into five sections, corresponding to major thematic areas related to physical layer security
The editorial team will provide perspectives for the chapters in each section
The two major forms of physical layer confidentiality will be covered-secrecy extraction and secrecy dissemination
Physical layer authentication will be discussed, providing a coverage of physical layer security that extends beyond the conventional "secrecy"-oriented approaches to security
