Abstract

An asymmetric single-channel color-image cryptosystem is presented that uses singular value decomposition and Tinkerbell map in the fractional Fourier domain. The input image is split into red, green, and blue channels. The red component is used as plaintext, and green and blue components are used as phase masks in the cryptosystem. MATLAB is used for computations of results presented in this paper. The proposed cryptosystem is validated for color images of size 256 × 256 × 3 pixels. The analysis of the attacks establishes the scheme’s resistance to occlusion and noise attack, and the key-space is big enough to endure a brute-force attack. The analysis based on the correlation distribution of neighboring pixels, along with statistical analysis has been performed to examine the efficacy of the cryptosystem. The results indicated high levels of security possessed by the proposed encryption scheme.
