Abstract
New image encryption algorithm based on chaotic dynamics and genetic algorithm elements has been proposed and implemented as software. This algorithm went through three stages: initialization, generation of cipher-images and genetic algorithm elements. The chosen value of information entropy in encrypted image was used as criteria for realization the generation of cipher-images stage and genetic algorithm elements stage of considered algorithm. The resistance of the encrypted algorithm to statistic and differential cryptographic attacks has been examined. The coefficients: NPCR (Number of Pixel Change Rate) and UACI (Unified Averaged Changed Intensity) were calculated to estimate the resistance of the image encryption algorithm. The productivity estimation of the image encryption algorithm has been carried out. The present image encryption algorithm may be to integrate in the apparatus means.
