Description
Summary:To obtain higher encryption efficiency and to realize the compression of quantum image, a quantum gray image encryption-compression scheme is designed based on quantum cosine transform and 5-dimensional hyperchaotic system. The original image is compressed by the quantum cosine transform and Zigzag scan coding, and then the compressed image is encrypted by the 5-dimensional hyperchaotic system. The proposed quantum image encryption-compression algorithm has larger key space and higher security, since the employed 5-dimensional hyperchaotic system has more complex dynamic behavior, better randomness and unpredictability than the low-dimensional hyper-chaotic system. Simulation and theoretical analyses show that the proposed quantum image encryption-compression scheme is superior to the corresponding classical image encryption scheme in term of efficiency and security.
