Quantum image encryption algorithm based on bit-plane permutation and sine logistic map

Quantum cryptography improves efficiency and security of image content protection owing to the characteristics of qubits. In this paper, a novel quantum image encryption algorithm based on bit-plane permutation and sine logistic map is presented. The image to be encrypted is firstly represented with novel enhanced quantum representation model and then the quantum Arnold transform is used to scramble pixel positions. The bit-plane cross-exclusive OR and shift operations are designed to change the pixel values. The final ciphertext image is obtained through a diffusion process utilizing sine logistic map, which extremely enlarges key space. The quantum circuits of each procedure are given. Simulation results and theoretical analysis verify that the proposed quantum image scheme has good performance in the aspect of security and the computational complexity is superior to its classical counterpart.
