Image Encryption Research based on chaotic sequences and wavelet transform
Using the characteristics of the chaotic system, such as ergodicity, sensitivity to initial condition, system parameters and random like behavior, this paper proposes a new image encryption algorithm based on chaotic sequences and wavelet transform. This algorithm controls the initial parameters of two onedimensional chaotic sequences through keys, generates the chaotic sequence, diffuses the image, and then does wavelet decomposition to the diffused image, finally, scrambles the image using two-dimensional hyper-chaotic sequences. The experimental results show that this algorithm has a good encryption effect and a high security.
