Universidad de Zaragoza Physical Layer Encryption for Industrial Ethernet in Gigabit Optical Links 2019 Access copy available to the general public Unrestricted Industrial Ethernet is a technology widely spread in factory floors and critical infrastructures where a high amount of data need to be collected and transported. Fiber optic networks at gigabit rates fit well with that type of environment, where speed, system performance, and reliability are critical. In this paper, a new encryption method for high-speed optical communications suitable for such kinds of networks is proposed. This new encryption method consists of a symmetric streaming encryption of the 8b/10b data flow at physical coding sublayer level. It is carried out thanks to a format preserving encryption block cipher working in CTR (counter) mode. The overall system has been simulated and implemented in a field programmable gate array. Thanks to experimental results, it can be concluded that it is possible to cipher traffic at this physical level in a secure way. In addition, no overhead is introduced during encryption, getting minimum latency and maximum throughput. info:eu-repo/grantAgreement/ES/MEC/FPU14-03523 info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2014-52840-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 7.515 2019 AUTOMATION & CONTROL SYSTEMS 4 / 63 = 0.063 2019 Q1 T1 INSTRUMENTS & INSTRUMENTATION 1 / 64 = 0.016 2019 Q1 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 16 / 266 = 0.06 2019 Q1 T1 2.911 2019 Computer Science Applications 2019 Q1 Electrical and Electronic Engineering 2019 Q1 Control and Systems Engineering 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0001-8648-6248 Garcia-Bosque, M.
