提出一种基于改进小波变换的多层量子图像加密算法。应用混沌序列和改进生成对抗网络,建立密钥池,对多层量子的明文图像进行置乱处理,通过重复两次FFT,得到最终的密文图像。为确保加密过程可逆性,改进小波变换重建多层量子图像。实验结果表明:研究方法对图像具有理想的加密效果,且解密后图像仍然可保持较高分辨率。

A multi-layer quantum image encryption algorithm based on improved wavelet transform is proposed.By applying chaotic sequences and improving generative adversarial networks,a key pool is established to scramble the plaintext images of multiple quantum layers.The final cipher text image is obtained by repeating FFT twice.To ensure the reversibility of the encryption process,the wavelet transform is improved to reconstruct multi-layer quantum images.The experimental results show that the research method has an ideal encryption effect on images,and the decrypted images can still maintain high resolution.
