Improve in Security Level of First Generation Chaotic Communication System by Mutual Synchronization

Abstract

We try to revive the first generation chaotic secure communication scheme by improving the degree of security level, using the concept of mutual chaotic synchronization. This provides additional robustness to secure communication systems designed for quality of service applications. This is aimed at obtaining a system which can generate very long streams of keys to be directly used for one-time stream ciphers (additive masking). The first generation scheme has the advantage of being easily implementable and uses less complex algorithm but have less degree of security. This proposed method is supposed to increase the degree of security level as it is protected against the parameter estimation attacks, which are a major threat to the identical synchronization schemes.
