MASKING OF MESSAGES USING THE DOUBLE SCROLL ATTRACTOR IN PRIVATE COMMUNICATIONS

Abstract

Message masking in private communication is described using a computer simulation of chaotic system such as double scroll oscillator. Mask of chaotic signal is added at the transmitter to the message. The received signal is used for synchronization and regenerating the masking signal at the receiver then subtrcting it from the received signal to recover the original message. An analog circuit of chaotic double scroll system is described and used to demonstrate possible approach to private communication based on synchronized chaotic system and high sensitivity to initial conditions.
