“…According to the number of blocks Bnum in Section 3.1.4, we divided the message encoding message into Bnum groups and used Section 3.2.2 to calculate the generated initial parameters of the system. According to the corresponding message encoding, we performed Bnum times of message encoding-controlled alternate quantum walks on the circle and finally generated a 3D probability amplitude matrix f re of size 2 * (Bsize * Bsize) * Bnum, whose expression is Equation (37). At the same time, a 3D probability distribution matrix Qum2D of size Bsize * Bsize * Bnum was generated, and its expression is Equation (38).…”

“…A discrete quantum walk ensures the security performance of the system through the infinite possibility of the initial state. It has similar characteristics to the chaotic dynamics in determining the walk state in the system, so it is used by researchers in image encryption models [35][36][37]. Yang et al [38] used the nonlinear chaotic dynamic performance of a quantum walk (QW) to construct a key generator with good performance, and based on this, they proposed an image encryption algorithm that combines quantum computing with image encryption, which has better security.…”

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

The hash function is an important branch of cryptology. Controlled quantum walk based hash function is a kind of novel hash function, which is safe, flexible, high-efficient, and compatible. All existing controlled quantum walk based hash functions are controlled by one bit message in each step. To process message in batch amounts, in this paper, controlled alternate quantum walk based block hash function is presented by using the time-positiondependent controlled quantum walks on complete graphs with self-loops. The presented hash function accelerate the hash processing dramatically, so it is more high-efficient.
