Lossless Frequency-Domain Image Encryption via 3D Exponential Hyper-Chaotic Map and Integer Lifting Wavelet Transform

To resolve the inherent conflict between high robustness and strict reversibility in frequency-domain image encryption, as well as to eliminate data expansion caused by floating-point errors, this paper presents a novel lossless frequency-domain image encryption scheme via 3D exponential hyper-chaos...
