Image Encryption Based on Reversible Cellular Automata
Zhihua Feng, Xu H · Journal of Liaoning University of Technology · 2008
A new approach to image encryption was proposed based on one dimensional reversible cellular automata(RCA).The encryption method can encrypt images with higher security because RCA rules and randomness of the data were used in the process of encryption.When using RCA to encrypt, such application converted the given gray level image into binary image and rearranges the data as a sequence of 0-1 data.The use of RCA's principles implemented image encryption.Simulation results for gray level images expatiated that the proposed encryption method satisfied the properties of confusion and diffusion.However,more perfect guess of encryption key made decryption impossible, this encryption method worked well as it's expectated.
