Fangtao Liu, Yu Liu · International Journal of Hybrid Information Technology · 2016
An image encryption method was built based on Lorenz chaotic mapping and finite field theory.First, original image information was divided into two image matrix by using Lorenz chaotic mapping.Second, five step calculations were finished about these two image matrix in the finite field.By combination of chaotic mapping and computing in the finite field, the new encryption method has a good effect and a fast speed.And the new encryption method realize the balance of speed and effect.Experimental results show that the proposed method has good encryption effect, attack resistance, the ideal speed of execution.
