Abstract

A new method based on the concept of virtual optics for both encryption and decryption is proposed. The technique shows the possibility to encrypt/decrypt digital information. Virtual wavelength, virtual focal length, and virtual diffractive distance can all be used to design locks and keys for image encryption. Numerical experiments are presented to test the effectiveness of the method. The possible dimensions of keys are roughly estimated and show a high security level.
