Universidad de Zaragoza Self-synchronized Encryption for Physical Layer in 10Gbps Optical Links 2019 Access copy available to the general public Unrestricted In this work a new self-synchronized encryption method for 10 Gigabit optical links is proposed and developed. Necessary modifications to introduce this kind of encryption in physical layers based on 64b/66b encoding, such as 10GBase-R, have been considered. The proposed scheme encrypts directly the 64b/66b blocks by using a symmetric stream cipher based on an FPE (Format Preserving Encryption) block cipher operating in PSCFB (Pipelined Statistical Cipher Feedback) mode. One of the main novelties in this paper is the security analysis done for this mode. For the first time, an expression for the IND-CPA (Indistinguishability under Chosen-Plaintext Attack) advantage of any adversary over this scheme has been derived. Moreover, it has been concluded that this mode can be considered secure in the same way of traditional modes are. In addition, the overall system has been simulated and implemented in an FPGA (Field Programmable Gate Array). An encrypted optical link has been tested with Ethernet data frames, concluding that it is possible to cipher traffic at this level, getting maximum throughput and hiding traffic pattern from passive eavesdroppers. info:eu-repo/grantAgreement/ES/MEC/FPU14-03523 info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2014-52840-R info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2017-85867-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.711 2019 0.943 2019 ENGINEERING, ELECTRICAL & ELECTRONIC 111 / 266 = 0.417 2019 Q2 T2 Computational Theory and Mathematics 2019 Q1 COMPUTER SCIENCE, HARDWARE & ARCHITECTURE 19 / 53 = 0.358 2019 Q2 T2 Theoretical Computer Science 2019 Q1 Software 2019 Q1 Hardware and Architecture 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0001-8648-6248 Garcia-Bosque, M.
