Abstract: A single-channel color image encryption is proposed based on iterative fractional
Fourier transform. The color image to be encrypted is first separated into three independent
channels: red, green and blue. Then, the red and green components are encrypted into a single
one based on iterative fractional Fourier transform. Similarly, the interim image and blue
component are encrypted into the final gray scale ciphertext with stationary white noise
distribution, which has camouflage property to some extent. In the process of encryption and
decryption, three different groups of fractional orders, five private phase functions and one
common phase function are used as keys to enhance the security of the proposed system.
Additionally, the proposed iterative fractional Fourier transform algorithm has faster convergent
speed. Simulation results verify the feasibility and effectiveness of this method. © 2012 IEEE.
