摘要：This paper presents an efficient encryption for low detailed image using logistic map and fractional Fourier transform (FrFT) in different modes of operation. The proposed cryptosystem employed logistic map with the FrFT using different modes of operation. The proposed cryptosystem is composed of two phases; encryption phase and decryption phase. The encryption phase began with applying the FrFT on the few detailed plain image. Then, the plain image is encrypted using logistic map in different operation modes. While in the decryption phase, this scenario will be reversed. The efficiency of the proposed image cryptosystem is investigated using different encryption quality metrics via simulation. The obtained results confirmed the viability of the proposed cryptosystem in CBC,CFB, and OFB operation modes. Moreover, the proposed system is successively applicable in terms of security encryption.
