Universidad de Zaragoza (orcid)0000-0001-8648-6248 A 1 Gbps Chaos-Based Stream Cipher Implemented in 0.18 m CMOS Technology 2019 Access copy available to the general public Unrestricted In this work, a novel chaos-based stream cipher based on a skew tent map is proposed and implemented in a 0.18 µm CMOS (Complementary Metal-Oxide-Semiconductor) technology. The proposed ciphering algorithm uses a linear feedback shift register that perturbs the orbits generated by the skew tent map after each iteration. This way, the randomness of the generated sequences is considerably improved. The implemented stream cipher was capable of achieving encryption speeds of 1 Gbps by using an approximate area of ~20,000 2-NAND equivalent gates, with a power consumption of 24.1 mW. To test the security of the proposed cipher, the generated keystreams were subjected to National Institute of Standards and Technology (NIST) randomness tests, proving that they were undistinguishable from truly random sequences. Finally, other security aspects such as the key sensitivity, key space size, and security against reconstruction attacks were studied, proving that the stream cipher is secure. info:eu-repo/grantAgreement/ES/MEC/FPU14-03523 info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2017-85867-R info:eu-repo/grantAgreement/ES/MINECO/TEC2014-52840 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.412 2019 ENGINEERING, ELECTRICAL & ELECTRONIC 125 / 265 = 0.472 2019 Q2 T2 0.303 2019 Electrical and Electronic Engineering 2019 Q2 Control and Systems Engineering 2019 Q3 Signal Processing 2019 Q3 Hardware and Architecture 2019 Q3 Computer Networks and Communications 2019 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Diez-Señorans, G.
