چکیده مقاله:

In this paper, a digital image encryption algorithm based on discrete wavelet transform and chaos theory is referred. The value of the discrete wavelet transformation coefficient matrixwas encrypted and the scrambled by adjusting chaos sequence. The proposed algorithm is described in detail. To illustrate theeffectiveness of the proposed scheme, some security analysis are presented. The cryptosystem speed is analyzed and tested as well.Results of the various types of analysis are encouraging and it can be concluded that the proposed image encryption techniqueis suitable choice for practical applications.
