A 3D Cuboid Image Encryption Algorithm Based on Controlled Alternate Quantum Walk of Message Coding

In order to solve various security risks faced by image privacy protection, we propose a 3D cuboid encryption scheme based on message-encoded controlled alternate quantum walks. Firstly, calculated the initial parameters of system and performed one-dimensional walk generate probability distribution sequence. Secondly, encoded sequence into quaternary message using multiple sets messages control model, generating amplitude matrix obtain hash through matrix. Then, was divided blocks integrated cuboid. The scrambled between layers value sequence, used complete scrambling cross-section layers. Finally, converted each pixel binary cube it perform rotation operation magnitude matrix, then XOR obtained tilted final encrypted image. simulation results show that can resist typical attacks has good performance.
