A Novel Chaotic Block Image Encryption Algorithm Based on Deep Convolutional Generative Adversarial Networks

Abstract: This paper proposes a novel chaotic block image encryption algorithm based on deep convolutional generative adversarial networks (DCGANs), quaternions, an improved Feistel network, and an overall scrambling and diffusion mechanism. First, a new hyperchaotic system is introduced and combined with DCGANs to generate a random sequence with better randomness and complexity as a key stream. This sequence is then combined with a quaternion and an improved Feistel network encryption of a colour plaintext image by uti… Show more

“…They reflect the degree of change after adjusting a specific pixel value of the plaintext image at random and show the link between the number of changes in the encrypted image's pixel values and the change degree. Even the slightest change in the plaintext image's pixel value can substantially alter the ciphertext image, which indicates that the encryption technique has a high resistance to differential attacks [40]. Table 8 demonstrates that the use of three color images evaluated the performance of opposing various attacks, and the findings suggest that this work is highly reliant on the input original image to deal with differential attacks.…”

“…A common use for neural networks in chaotic image encryption is to generate the key streams. This can be seen in a proposal by Han et al [175], where a Hermite chaotic network was trained from a logistic map, and in a proposal by Fang et al [251].…”

“…In [165], Fang et al proposed another block-based image encryption scheme that uses deep convolutional generative adversarial networks (DCGANs), quaternions, an improved Feistel network [166], and a comprehensive scramblingdiffusion process. Their proposed encryption scheme involved creating a new hyperchaotic system that is integrated with DCGANs to generate a complex key stream.…”
