A novel chaotic System For Color Image Encryption

Abstract

a new color image encryption algorithm is proposed by combining diffusion
the image pixel and keys that generating by a novel chaotic system. The
performance of the algorithm has been analyzed through analyzes statistical
such as histogram analysis, correlation coefficient analysis, Information
entropy analysis, key space analysis, key sensitivity analysis, and results show
that the algorithm has good encryption performance and high security due to
key space size can reach to 10308
which means that very long , and the high
sensitivity for small changes in key which makes the algorithm immune to
Brute force attacks, and it can resist the statistical attacks, so the key space
was large enough to resist many statistical attack methods, the algorithm has
been implemented and analysis done by using Matlab R2012b software.
