Abstract :
A novel method for the image encryption based on the Fractional Fourier Transform (FRFT) is proposed in this paper. Different sampling matrixes are introduced to analysis the multiplicity of the FRFT. This property is also used for the design of the encryption algorithm here. Good performance in the experiments shows its efficiency.
