The conventional approach for images encryption entails transforming a regular image into an encrypted image that resembles noise. However, this noise-like encrypted image is susceptible to drawing the attention of an attacker when transmitted throug

This paper proposes a Zigzag transform that starts at random positions and crosses bidirectionally (ZZBCRP) to scramble the image. The number of sequence types of this new Zigzag transform is the number of pixels in the plaintext image, which is more

To solve the problem of the low secret space and security of some image schemes, a novel 4D chaotic system is derived in this paper. Compared with other similar chaotic systems, the new system only has one equilibrium point and can exhibit hyperchaot
