© 2022 Elsevier B.V.This paper proposes a novel quantum image encryption algorithm based on a local substitution and global permutation scheme. First, a plaintext-related secret key is generated by using a hyperchaotic system; second, the plain image is scrambled employing a block-based general Arnold transform and permutation-based special linear transform; third, S-box substitution and special linear transform are iterated multiple times until certain conditions are achieved. A novel controlled alternated quantum walks scheme is also proposed to generate substitution boxes. Numerical simulation shows that the proposed encryption scheme can effectively a encrypt plain image to an incomprehensible noise image, and is capable of resisting a variety of attacks.
