A new algorithm of encryption and decryption of image using combine chaotic mapping

الملخص EN

The work in this research demonstrates a color image encryption decryption algorithm by utilities chaotic maps to generated pseudo number generator.

In this research combine two Logistic maps to generate the Key.

The key generated is used in confusion and diffusion stages.

Through the confusion stage is permutated the pixel of image while in diffusion stage the value for each pixel is change.

The security and performance of this techniques has been analysis through statically analysis and key space analysis.

The data has been shown that the performance for this algorithm was very accurate and fast.
