Universidad de Zaragoza Chaos-Based Bitwise Dynamical Pseudorandom Number Generator on FPGA 2019 Access copy available to the general public Unrestricted In this paper, a new pseudorandom number generator (PRNG) based on the logistic map has been proposed. To prevent the system to fall into short period orbits as well as increasing the randomness of the generated sequences, the proposed algorithm dynamically changes the parameters of the chaotic system. This PRNG has been implemented in a Virtex 7 field-programmable gate array (FPGA) with a 32-bit fixed point precision, using a total of 510 lookup tables (LUTs) and 120 registers. The sequences generated by the proposed algorithm have been subjected to the National Institute of Standards and Technology (NIST) randomness tests, passing all of them. By comparing the randomness with the sequences generated by a raw 32-bit logistic map, it is shown that, by using only an additional 16% of LUTs, the proposed PRNG obtains a much better performance in terms of randomness, increasing the NIST passing rate from 0.252 to 0.989. Finally, the proposed bitwise dynamical PRNG is compared with other chaos-based realizations previously proposed, showing great improvement in terms of resources and randomness. 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/ 3.658 2019 INSTRUMENTS & INSTRUMENTATION 9 / 64 = 0.141 2019 Q1 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 65 / 266 = 0.244 2019 Q1 T1 1.027 2019 Instrumentation 2019 Q1 Electrical and Electronic Engineering 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Perez-Resa, A.
