OBSERVER-BASED CHAOS ANTI-SYNCHRONIZATION METHOD AND ITS APPLICATION IN SECURE ENCRYPTION

Original language description

The use of chaos for communication is a relatively new field of research. The design of communication schemes that are based on chaotic dynamics was studied during the last decade, while the study of traditional communication has began a century ago. Inthis paper, a modified version of the Chaos Shift Keying (CSK) scheme for secure encryption and decryption of data is proposed. The proposed scheme uses the effect of anti-synchronization, rather than synchronization. More specifically, the classical CSKmethod determines the correct value of binary signal through checking which unsynchronized system is getting synchronized. On the contrary, our novel method determines wrong value of binary signal through checking which already synchronized system is loosing synchronization. Our method is implemented and thoroughly tested on the recently introduced generalized Lorenz system (GLS) family making advantage of its special parametrization.

Anti-synchronizace chaosu pomocí nelineárního pozorovatele a její využití k chaotickému šifrování

Czech description

Článek popisuje novou metodu šifrování založenou na chaosu a jeho synchronizaci. Metoda rozpoznává příslušné bity pomocí detekce anti-synchronizace dříve ideálně synchronizovaného chaotického systému. Kvantitativně detailně zkoumá rychlost takové desynchronizace a minimalizuje tak čas a množství dat potřebných na zakódování jednoho bitu.
