Such a synchronization may be used for chaotic masking scheme using a single channel only. This method was already discussed in the earlier literature for the particular classes of systems. In this paper, a more general class wheremessage embedded synchronization is possible is described. Then, it is shown that the generalized Lorenz system falls within that class. Furthermore, using the resulting synchronization, the novel secure encryption scheme is proposed. It requires very reasonable amount of data to encrypt and time to decrypt one bit. Basically, to encrypt one bit, only one iteration (i.e. only one real number of 6 valid digits) is needed. At the same time, 100 percent of the carrying chaotic signal can be used. The method is also demonstrated by numerical simulations of a digital data encryption and decryption. cav_un_auth*0291709 Nostradamus 2013 Ostrava 03.06.2013-05.06.2013 CZ 2014 BC 2 PR RVO:67985556 http://hdl.handle.net/11104/0221978 2013 textový dokument 232 kB cav_un_epca*0392920 Nostradamus 2013: Prediction, Modeling and Analysis of Complex Systems Advances In Intelligent Systems and Computing 210 978-3-319-00541-6 2194-5357 313 322 Cham Springer 2013 Zelinka I. 340 Chen G. 340 Rossler O.
