Synchronized hybrid chaotic generators: Application to real-time wireless speech encryption
چکیده انگلیسی

In this paper, a new stream key generator Hybrid Discrete Continuous Chaotic System (HDCCS) based on continuous and discrete chaotic systems is proposed. Our solution provides an easy and robust chaos synchronization while decrease the degradation due to finite precision during a digital implementation. Real-time application to wireless speech encryption effectively hides the original signal. Statistical security analysis for the proposed cryptosystem against cryptanalysis attacks, from a strict cryptographic viewpoint, are presented. These results verify and prove that the proposed speech cryptosystem is highly secure and has a very powerful diffusion and confusion mechanisms widely used in conventional cryptography.


► Proposition of a new chaotic generator system with a high complex chaotic behavior.
► The proposed key passes successfully the NIST statistical tests.
► Our proposed cryptosystem scheme presents high robustness against cryptanalysis.
► Our efficient stream key generator is useful for real time speech encryption.
► Our proposed cryptosystem can be widely used in real time encryption data.
