Abstract

The proposed cryptosystem avoids all the crypto graphical weaknesses of earlier chaos-based encryption systems. Number of security analysis were carried out on the new algorithm and simulation results show that encryption and decryption are good and the proposed chaotic algorithm is proven to be the good procedure in terms of robustness.
