A Color Image Encryption Scheme Using Inverse Fractal Interpolation Function

A color image encryption scheme based on inverse fractal interpolation function has been proposed. The inverse fractal interpolation function owns good chaotic natures and therefore can be applied to generate pseudo-random sequences to scramble the plain image pixel positions and then diffuse the scrambled image to get ideal cipher-image. The performance and security analysis of the proposed image encryption scheme have been carried out, including key sensitivity analysis, histogram analysis, correlation analysis, entropy analysis, and differential attack analysis, etc. Results show that the proposed image encryption scheme is secure enough to be adopted for the secure image communication applications.
