Cruz-Hernández Física, Astronomía y Matemáticas Lorenz system Chaos synchronization private communications In this work, a modified chaos-based communication scheme is presented. In particular, we extend the basic scheme for chaotic maskingusing a single transmission channel proposed by Cuomo and coworkers in 1993. The substantial differences between the traditional schemeand this modified one, significantly affect the reception quality of the sent message, such that this one can faithfully be recovered withoutfiltering at the receiver end, without considering the effect of noise in the transmission channel. Nevertheless, if noise is present, this canbe eliminated using a filtering stage. We use two Lorenz systems unidirectionally coupled, the first like a master/transmitter system and theother like a slave/receiver system in order to illustrate with some numerical simulations the effectiveness of the modified scheme. 2005 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57063907 https://www.redalyc.org/journal/570/57063907/ https://www.redalyc.org/journal/570/57063907/html/ https://www.redalyc.org/journal/570/57063907/57063907.epub https://www.redalyc.org/journal/570/57063907/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
