Paper Abstract
We propose a new optical symmetric cryptographic system with simultaneous encryption and transmission of binary
data and secret key by using dual phase-shifting digital holography. Dual phase-shifting digital holography contains two
inner and outer interferometers which are used for encrypting data and a secret key at the same time. The technique using
dual phase-shifting digital holographic interferometry is efficient because this scheme has an advantage of interference
fringe data acquiring time. Binary information data is encrypted by the secret key by applying phase-shifting digital
holographic method, and this secret key is also encrypted by phase-shifting digital holographic method and transmitted.
Encrypted digital hologram in our method is Fourier transform hologram and is recorded on CCD with 256 gray-level
quantized intensities. These encrypted digital holograms are able to be stored by computer and be transmitted over a
communication network. With this encrypted digital hologram, the original binary data are decrypted by the same secret
key. Simulation results show that the proposed method can be used for a cipher and security system.
