Optical encryption based on iterative fractional Fourier transform
We propose a new architecture that encodes a primary image to white noise based on iterative fractional Fourier transform. The parameters of the fractional Fourier transform can provide additional keys for encryption to make the code more difficult to break. Numerical simulation results are given to...

| description | We propose a new architecture that encodes a primary image to white noise based on iterative fractional Fourier transform. The parameters of the fractional Fourier transform can provide additional keys for encryption to make the code more difficult to break. Numerical simulation results are given to demonstrate the flexibility of this new proposed method and an optical implementation is also suggested. |
