Wavelet Image Encryption Algorithm Based on AES
Wu Xiao Meng · 中国邮电高校学报：英文版 · 2002
Traditional encryption techniques have some limits for multimedia information, especially image and video, which are considered only to be common data. In this paper, we propose a wavelet based image encryption algorithm based on the Advanced Encryption Standard, which encrypts only those low frequency coefficients of image wavelet decomposition. The experimental results are satisfactory.
