TL;DR
The proposed scheme for synchronization of chaos, whereby one combines the original Pecora and Carrols procedure with an adaptive algorithm for chaos control, provides synchronization between a message sender and a message receiver and assures security in the communication against external interceptions.
Abstract
We introduce a scheme for synchronization of chaos, whereby one combines the original Pecora and Carrols [Phys. Rev. Lett. 64, 821 (1990)] procedure with an adaptive algorithm for chaos control. Based upon the knowledge of the local variation rates, the algorithm provides synchronization between a message sender and a message receiver and assures security in the communication against external interceptions. The effectiveness of the proposed scheme as well as its robustness are shown for the Lorenz system.
