Abstract
In this paper, a new selective encryption scheme based on DWT, AES S-box and chaotic permutation is proposed. The new scheme is composed of six steps: Image decomposition, Block permutation, DWT decomposition, substitution phase, chaotic permutation phase and reconstruction phase. Firstly, it generates four subbands, namely cAP, cVP, cHP and cDP, and encrypts only cAP subband, which contains the meaningful part of data. The proposed cryptosystem is evaluated using various security and statistical analysis. The performance tests show that the proposed scheme is secure against statistical and differential attacks.Keywords
