As an important field in information security, image encryption algorithm has been a research focus. At the same time there are few works on fractal set as the encryption key among various encryption algorithms. In the paper, Mandelbrot set (abbreviated as M set) and the Hilbert transformation are utilized to generate the random key. Since M set can be iterated from only a few parameters, it can reduce...
This paper analyzes a new image encryption scheme proposed in "A new encryption based on Henon mapping" and proves that this encryption algorithm is insecure in the image-known attack. By analyzing the properties of the round function, there are two weaknesses: on the one hand, the confusing process will not completely destroy the correlation of image pixels, on the other hand, because of...
This paper proposes a novel encryption scheme based on invertible watermarking. In the past encryption algorithms, diffusion and confusion algorithms are used to increase the effect of the encryption, however, these algorithms can only change the cover itself to be encrypted. In this paper, the invertible watermarking can be used to perform the encryption, which can not only use the additional information...
