Abstract: A new method based on the concept of virtual optics for both encryption and decryption is proposed. The technique shows the possibility to encode/decode any digital information. A virtual wavelength and a pseudo-random covering mask (PRCM) are used to design ?double locks? and ?double keys? for image encryption. Numerical experiments are presented to test the sensitivity of the virtual wavelength. The possible dimensions of keys are roughly estimated and show a high security level.
