Synchronization of Quadratically Damped Mathieu ? Duffing Based Chaotic Circuits with Applications to Secure Communications

This paper presents an effective secure chaotic synchronized communication using quadratically damped Mathieu Duffing system. The circuit simulation results are used to visualize and illustrate the effectiveness of quadratically damped Mathieu - Duffing chaotic system in synchronization and application of secure communication. The synchronization between two chaotic oscillators, serving as a transmitter-receiver scheme using one way coupling is studied.
