Scheme of Image Encryption Based on New Cascading Chaos
SU Jin-hai · Science Technology and Engineering · 2007
A new sequence is yielded from logistic map, which is initialized by three dimensions chaotic sequences of Chua's chaotic system. Then the new sequence is analyzed from the view of cryptology. The result proves that it has excellent randomicity and is adopted as spreading spectrum sequence. In the end, image encryption and decryption with the new sequence are studied. Simulation and security analysis show that the sequence overcomes latent attack in single chaotic system and enlarges the key space. It can withstand the attack by phase space reconstitution effectively. [
