Observer-Based Chaos Synchronization And Its Application to Multi-Valued Alphabet Chaos Shift Keying Secure Encryption
Original language description
This paper studies possible application of the observerbased chaos synchronization to secure encryption. Unlike common approaches that use continuous time synchronized chaos for the so-called chaotic masking, the chaos shift keying (CSK) is being used here. CSK uses piece of synchronized chaotic signal to encode directly a given symbol. This paper uses properties of observer-based synchronization to achieve reasonable amount of information per symbol, moreover, specific properties of dependence of thisobserver-based synchronization on parameters make possible direct encryption of multi-alphabet symbols. Such a breakthrough is enabled by using anti-synchronization effect, rather than the synchronization one. Our method, further referred as the anti-synchronization chaos shift keying (ACSK), is implemented and thoroughly tested on the recently introduced generalized Lorenz system (GLS) family making advantage of its special parametrization.
