Device Fingerprint as a Transmission Security Paradigm

Optoelectronics plays a crucial role in the field of telecommunications and networks. Specifically, optoelectronic constructions serve as sources, detectors, and light controllers in communication and optical network systems. One of the require-ments of a secure system is evaluating the optical components of optoelectronic assemblies and ensuring their security against malicious attacks. To address this, we introduce the concept of optical fingerprints in optical communications and networks. This concept includes reading the fingerprints of devices, sub-systems, and systems to address services that comprise security, authentication, identification, and monitor-ing. Using optical fingerprints as a signature of optical fibers, it becomes possible to identify and evaluate any optical component of optoelectronic assemblies through their pigtail.
