A novel color image encryption algorithm based on genetic recombination and the four-dimensional memristive hyperchaotic system

摘要: Recently, many image encryption algorithms based on chaos have been proposed. Most of the previous encrypt components R, G, and B color images independently neglect high correlation between them. In paper, a novel algorithm is introduced. The 24 bit planes plain are obtained recombined into 4 compound planes, this can make three affect each other. A four-dimensional (4D) memristive hyperchaotic system generates pseudorandom key streams its initial values come from SHA 256 hash value image. confused according to principles genetic recombination, then confusion diffusion as union applied cipher obtained. Experimental results security analyses demonstrate that proposed secure effective so it may be adopted for communication.
