Galois field refers to a field in which there exist finitely many elements. It is particularly useful in translating computer data as they are represented in binary forms. Galois operations match those of regular math. In this paper, the authors are using the existing passcode based approach of hiding classified information in images with addition of the Galois field theory, which is advancing the security level to make this combination method extremely difficult to intercept and useful for open channel communication while maintaining the losses and high speed transmission.
