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. 000079573 536__ $$9info:eu-repo/grantAgreement/ES/MEC/FPU14-03523$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2014-52840-R 000079573 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000079573 590__ $$a7.515$$b2019 000079573 591__ $$aAUTOMATION & CONTROL SYSTEMS$$b4 / 63 = 0.063$$c2019$$dQ1$$eT1 000079573 591__ $$aINSTRUMENTS & INSTRUMENTATION$$b1 / 64 = 0.016$$c2019$$dQ1$$eT1 000079573 591__ $$aENGINEERING, ELECTRICAL & ELECTRONIC$$b16 / 266 = 0.06$$c2019$$dQ1$$eT1 000079573 592__ $$a2.911$$b2019 000079573 593__ $$aComputer Science Applications$$c2019$$dQ1 000079573 593__ $$aElectrical and Electronic Engineering$$c2019$$dQ1 000079573 593__ $$aControl and Systems Engineering$$c2019$$dQ1 000079573 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000079573 700__ $$0(orcid)0000-0001-8648-6248$$aGarcia-Bosque, M.$$uUniversidad de Zaragoza 000079573 700__ $$0(orcid)0000-0002-8236-825X$$aSánchez-Azqueta, C.$$uUniversidad de Zaragoza 000079573 700__ $$0(orcid)0000-0003-0182-7723$$aCelma, S.$$uUniversidad de Zaragoza 000079573 7102_ $$12002$$2385$$aUniversidad de Zaragoza$$bDpto.
