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 (2 8 ) is used. The encryption is done on pixel values of the RGB co… Show more
