RF nanostructured security

Abstract

This chapter gives an intensive overview of some recent micro‐ and nanostructured Radio Frequency (RF) security issues. It identifies the challenges of tomorrow’s security problems and why this has been a big relevance not only to nano-communications but also to other applications. A short overview on the traditional Physical Unclonable Functions (PUFs) introduces the reader into the concept of applied electromagnetic waves interacting with nanomaterials. Major security and fingerprinting contributions, which are newly‐proposed and implemented by the authors, are concluded in this chapter. These security techniques are based on artificially‐synthesized disordered micro and nano materials. A potential on‐chip realization and integration scenario of such approach is also discussed. Novel material synthesis technologies and functional prototype production processes are illustrated. Extraction process of RF fingerprints, based on near‐field scattering measurements, is included as well. Finally, statistical analysis and distance measures of similarity, uniqueness and orthogonality of the extracted fingerprints are carefully investigated at the end of this chapter.
