Contraction-Based Chaotic Fractional-Order System Synchronization for Message Encryption

Resumen: In this work it is presented a contraction analysis-based design for the synchronization of a pair of chaotic fractional order systems is presented. It allows to send encrypted information through a channel, using the chaotic sequence generated by a master system as a carrier signal to the second slave system which decrypts the message using a key signal. Contraction analysis gives a straightforward analysis design, one given for the synchronization and convergence of neighbor trajectories of both systems. Numeric examples are presented to show the effectiveness of the proposed design.
