The application of Galois fields operation with chaos mapping in digital image encryption
Bing Liu, Qiang Chen · 2017
A new digital image encryption method is proposed by introducing a chaos mapping combining matrix operations on Galois fields.The original image is mapped into two matrices by using chaos mapping, and then the original image matrix is processed sequentially with the two matrices over a Galois field to obtain the encrypted image.The experimental results show that the proposed method can obtain more uniform and fine scrambling effect than the traditional one, it has a stronger anti-jamming performance and faster encryption speed.
