Study of Generating 4D and 5D Coexisting Hyper Chaotic Autonomous Systems for Application in Cryptography

The chaos has found extensive application in information processing, biomedical application and cryptography. In this paper, 4D and 5D hyper chaotic systems were investigated for hyper chaotic and coexisting attractors. The dynamics of the both the systems were implemented using MATLAB. These systems shown coexisting attractors based on varying initial conditions which can increase the encryption space in secure communication applications. Hence, both the hyper chaotic systems were examined for secure data communication using MATLAB-Simulink and the information signal was encrypted and transmitted using chaotic masking method. At the receiver side the encrypted message was decrypted successfully.
