Necessary modifications to introduce encryption in Ethernet 10GBase-R standard have been considered. This security enhancement has consisted of a symmetric streaming encryption of the 64b/66b data flow at physical coding sublayer level thanks to two keystream generators based on a chaotic algorithm. The overall system has been implemented and tested in a field programmable gate array. Ethernet traffic has been encrypted, transmitted, and decrypted over a multimode optical link. Experimental results are analyzed concluding that it is possible to cipher traffic at this level and hide the complete Ethernet traffic pattern from any passive eavesdropper. In addition, no overhead is introduced during encryption, getting no losses in the total throughput. 000084168 536__ $$9info:eu-repo/grantAgreement/ES/MEC/FPU14-03523$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2014-52840-R$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2017-85867-R 000084168 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000084168 590__ $$a3.318$$b2019 000084168 591__ $$aENGINEERING, ELECTRICAL & ELECTRONIC$$b74 / 266 = 0.278$$c2019$$dQ2$$eT1 000084168 592__ $$a1.038$$b2019 000084168 593__ $$aElectrical and Electronic Engineering$$c2019$$dQ1 000084168 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000084168 700__ $$0(orcid)0000-0001-8648-6248$$aGarcia-Bosque, M.$$uUniversidad de Zaragoza 000084168 700__ $$0(orcid)0000-0002-8236-825X$$aSanchez-Azqueta, C.$$uUniversidad de Zaragoza 000084168 700__ $$0(orcid)0000-0003-0182-7723$$aCelma, S.$$uUniversidad de Zaragoza 000084168 7102_ $$12002$$2385$$aUniversidad de Zaragoza$$bDpto.
