In this paper, we propose to enhance the security performance of the color
image encryption algorithm which depends on multi-chaotic systems. The
current cryptosystem utilized a pixel-chaotic-shuffle system to encode
images, in which the time of shuffling is autonomous to the plain-image.
Thus, it neglects to the picked plaintext and known-plaintext attacks. Also,
the statistical features of the cryptosystem are not up to the standard. Along
these lines, the security changes are encircled to make the above attacks
infeasible and upgrade the statistical features also. It is accomplished by
altering the pixel-chaotic-shuffle component and including another pixel-chaotic-diffusion system to it. The keys for diffusion of pixels are extracted
from the same chaotic arrangements created in the past stage. The renovation
investigations and studies are performed to exhibit that the refreshed version
of cryptosystem has better statistical features and invulnerable to the picked
plaintext and known plaintext attacks than the current algorithm.
