Optical Encryption for Data Security

Introduction

Encryption is the transformation of data into a form that is nearly impossible to read without the appropriate key. for data security applications, optical systems offer many degrees of freedom like phase, spatial frequency and polarization, to encode the data more securely. Opto-electronic encryption systems incorporating polarization encoding and fractional Fourier plane encoding have been developed. These systems are based on double random phase encoding and polarization based XOR operation encoding techniques. Efficient encryption and decryption in view of blind decryption cases have been carried out.

Salient features:

High speed data encryption and decryption. Enhanced security. PC based user interface.
