The application of chaotic mapping based on finite field operation in digital image encryption

A new digital image encryption method is proposed by introducing a high-dimensional chaotic mapping and combining matrix operation in finite field. The original image is mapped into two dimensional matrices by using chaotic mapping, and then the original image matrix and the previously generated two matrices are successively subjected to a multiplication operation in finite field. The experimental results show that the proposed encryption method can obtain more uniform and detailed image scrambling effect than the traditional method, has stronger anti-jamming performance and faster execution efficiency, and has better performance in image secure storage and communication Value.
