An Image Encryption Algorithm Based on Discrete-Time Alternating Quantum Walk and Advanced Encryption Standard

Guangzhe Liu, Wei Li, Xingkui Fan, Zhuang Li, Yuxuan Wang, Hongyang Ma
This paper proposes an image encryption scheme based on a discrete-time alternating quantum walk (AQW) and the advanced encryption standard (AES).  ...  The technology is based on simulation verification, including pixel correlation, histograms, differential attacks, noise attacks, information entropy, key sensitivity, and space.  ...  Based on the original AES algorithm, we combined quantum technology with the AES algorithm and used an alternating quantum walk (AQW) to generate a matrix with quantum properties.  ...
