Abstract EN
We propose a new and efficient method to develop secure image-encryption techniques.
The new algorithm combines two techniques: encryption and compression.
In this technique, a wavelet transform was used to decompose the image and decorrelate its pixels into approximation and detail components.
The more important component (the approximation component) is encrypted using a chaos-based encryption algorithm.
This algorithm produces a cipher of the test image that has good diffusion and confusion properties.
The remaining components (the detail components) are compressed using a wavelet transform.
This proposed algorithm was verified to provide a high security level.
A complete specification for the new algorithm is provided.
Several test images are used to demonstrate the validity of the proposed algorithm.
The results of several experiments show that the proposed algorithm for image cryptosystems provides an efficient and secure approach to real-time image encryption and transmission.
