Abstract

In the past few years, study of securing the digital images has increased tremendously and several encryption algorithms based on Cellular Automata have been proposed to protect the digital images against different cryptographic attacks. This paper proposes a novel pixel based encryption scheme based on Cellular Automata and Galois Field. Here the random key image has been generated using 1D Cellular Automata and for the encryption purpose GF (28) is used. The encryption is done on pixel values of the RGB components separately. Since this cryptosystem uses only logic operations for both key generation and GF (28) operations, it requires minimized computational resources and the execution speed is also high. Experimental results exhibit the confusion and diffusion properties of the proposed system. The correlation analysis shows that the proposed scheme has zero correlation amongst adjacent pixels (horizontal, vertical, diagonal).
