TLDR
A novel architecture for optical image encryption based on interference is proposed that does not need iterative encoding and the parameters of the configuration can also serve as additional keys for encryption.Abstract:
We proposed a novel architecture for optical image encryption based on interference. The encryption algorithm for this new method is quite simple and does not need iterative encoding. The parameters of the configuration can also serve as additional keys for encryption. Numerical simulation results demonstrate the flexibility of this new proposed method.read more
