Abstract: Many researches called for the producing new encryption algorithms as a method of protecting the information from unauthorized persons when stored or transmitted over the internet. A new method to encrypt the RGB image is presents by this research. This method is relied on three levels to make security better and provide an encrypted image with a few correlation pixel, high degree of entropy and histogram has a distributed uniform, first level, dividing the image into two equal parts. Second level, encrypting the information of each part using a secret key generated by using 1D logistic mapping. Third level, permutation the pixels position using random numbers generated by using LFSRs. Several tests done to verify that the suggested encryption method is safe.
