چکیده انگلیسی
In this paper, we propose a partial compression-encryption of images using chaotic system and Discrete Wavelet Transform (DWT) combined with Set Partitioning in Hierarchical Trees (SPIHT). The proposed cryptosystem adopts three stages for confusion and diffusion which are well integrated into the compression chain. The chaotic system used in this approach is Chirikov Standard Map. Some cryptographic tests and metrics are applied to measure the degree of security and analyze the performance of the partial compression-encryption scheme. The evaluation and simulation analysis indicate that our proposal possesses excellent statistical and cryptographic properties; it is extremely sensitive to the small change in secret key, resists against common cryptanalytic attacks, has a high speed and provides high picture quality of the reconstructed image.
