Abstract
This paper proposes a novel image encryption algorithm based on the discrete fractional Fourier transform and an improved magic cube rotation scrambling algorithm. Through fractional Fourier transform and position scrambling, the proposed algorithm can achieve double image encryption in the time-frequency domain. Compared the encrypted images and decrypted images, the proposed image encryption algorithm has better performance than only using fractional Fourier transform.
