This kind of encryption is called FPE (Format Preserving Encryption). Currently, only two AES (Advanced Encryption Standard) modes of operation recommended by the NIST (National Institute of Standards and Technology) are able to implement FPE algorithms, FF1 and FF3. These modes work in an electronic codebook fashion and can be configured to encrypt databases with an arbitrary format and length. However, there are no stream cipher proposals able to implement FPE encryption for high data rate information flows. The main novelty of this work is a new block cipher operation mode proposal to implement an FPE algorithm in a stream cipher fashion. It has been called CTR-MOD and it is based on a standard block cipher working in CTR (Counter) mode and a modulo operation. The confidentiality of this mode is analyzed in terms of its IND- CPA (Indistinguishability under Chosen Plaintext Attack) advantage of any adversary attacking it. Moreover, the encryption scheme has been implemented on an FPGA (Field Programmable Gate Array) and has been integrated in a Gigabit Ethernet interface to test an encrypted optical link with a real high data rate traffic flow. info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2017-85867-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.367 2020 COMPUTER SCIENCE, INFORMATION SYSTEMS 65 / 162 = 0.401 2020 Q2 T2 TELECOMMUNICATIONS 36 / 91 = 0.396 2020 Q2 T2 ENGINEERING, ELECTRICAL & ELECTRONIC 94 / 273 = 0.344 2020 Q2 T2 0.586 2020 Computer Science (miscellaneous) 2020 Q1 Materials Science (miscellaneous) 2020 Q1 Engineering (miscellaneous) 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Garcia-Bosque, Miguel Universidad de Zaragoza (orcid)0000-0001-8648-6248 Sanchez-Azqueta, Carlos Universidad de Zaragoza (orcid)0000-0002-8236-825X Celma, Santiago Universidad de Zaragoza (orcid)0000-0003-0182-7723 2002 385 Universidad de Zaragoza Dpto.
