These seeds have then been used in a chaotic stream cipher based on a Modified Logistic Map and a Linear Feedback Shift Register. The sequences generated by the chaotic stream cipher have been subjected to the randomness NIST tests. All the tests have been passed, proving that the proposed approach could be used for secure communications.2016http://zaguan.unizar.es/record/7066910.1016/j.proeng.2016.11.485http://zaguan.unizar.es/record/70669oai:zaguan.unizar.es:70669info:eu-repo/grantAgreement/ES/MEC/FPU14-03523info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2011-23211info:eu-repo/grantAgreement/ES/MINECO-FEDER/TEC2014-52840-RProcedia Engineering 168 (2016), 1663-1666by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
