Double Quantum Image Encryption Based on Arnold Transform and Qubit Random Rotation

Blog Article

Quantum image encryption offers major advantages over its classical counterpart in terms of key space, computational complexity, and so on.A novel double quantum image encryption approach based on quantum Arnold transform (QAT) and qubit random rotation is proposed in this paper, in which azalea mrs gg gerbing QAT is used to scramble pixel positions and the gray information is changed by utilizing random qubit rotation.Actually, the independent random qubit rotation operates once, respectively, in spatial and frequency domains with the help of luau thank you cards quantum Fourier transform (QFT).The encryption process accomplishes pixel confusion and diffusion, and finally the noise-like cipher image is obtained.

Numerical simulation and theoretical analysis verify that the method is valid and it shows superior performance in security and computational complexity.
