Abstract

Chaos-based secure communication systems are alternative of standard spread-spectrum systems that enable spreading the spectrum of the information signals and encrypting information signals with simple and inexpensive chaotic circuitry. In secure communication area, like Lorenz, Chua, Rossler, Duffing etc, classical systems are widely used. Malasoma chaotic system is topologically simple but their dynamical behaviors are non-linear synchronization and secure communication applications has not seen in paper. This paper aims for introducing a new chaotic system which is able to use as alternative to classical chaotic systems into secure communication fields. In addition, this new model simulates a synchronous communication system using P-C (Pecora-Carroll) method by verifying security with chaos signal through simulation. Modelling, synchronization and secure communication applications of Malasoma are realized respectively in MATLAB-Simulink environment. Retrieved results show that this novel chaotic system is able to use in secure communication fields.

카오스 기반 보안 통신시스템은 표준 대역확산 시스템의 대안으로서, 이것은 정보신호의 대역을 확산시키며 단순하고 작은 비용으로 카오스회로를 사용하여 정보신호를 암호화할 수 있다. 보안 통신 분야에서는 Lorenz, Chua, Rossler, Duffing등과 같은 전통적인 시스템들이 널리 사용되고 있다. Malasoma 카오스 시스템은 위상학적으로는 단순하지만 불규칙한 신호 생성과 비선형성의 시스템으로서 동기화와 보안 통신을 적용한 시스템은 관련 논문도 거의 없다. 본 논문은 기존의 카오스 시스템의 대안으로서 보안 통신 분야에서 사용될 수 있는 새로운 카오스 시스템을 소개한다. 또한 이 새로운 모델은 시뮬레이션을 통하여 카오스 신호로 보안성을 확인하고 P-C(Pecora-Carroll)방식을 사용하는 동기화 통신시스템을 모델화 한다. Malasoma 시스템의 모델링, 동기화 및 보안 통신 응용은 각각 MATLAB - Simulink 환경에서 구현된다. 이를 통해 도출된 결과는 이 새로운 카오스 시스템이 보안 통신 분야에서 사용될 수 있음을 확인할 수 있다.
