- Abstract
A new quantum multi-image compression and encryption algorithm combining quantum discrete cosine transform with 4D hyper-chaotic Henon map is proposed. The four original images are firstly transformed by quantum discrete cosine transform, and then the obtained frequency coefficient matrices are compressed with the measurement matrices to construct four compressed images. Subsequently, four compressed images are selected to reconstruct a new quantum image. Under the control of four initial values and two parameters, a quantum key image is constructed by a 1D chaotic sequence originated from the 4D hyper-chaotic Henon map, and XORed with the reconstructed quantum image. Ultimately, to enhance the security of the algorithm, the cycle shift operations controlled by the logistic map are employed to scramble the pixels of the produced quantum image to acquire the encryption image. Numerical simulations confirm the reliability and the security of the designed quantum multi-image compression and encryption algorithm.
