A Dual Encryption Scheme of Images Using Polarized Light
Résumé
Motivated by recent interest in polarization encoding, we propose and analyze a dual encryption/decryption scheme. Compared to standard optical encryption methods which are based on phase and amplitude manipulation, this encryption procedure relying on Mueller- Stokes formalism provides a large flexibility in the key encryption design. The effectiveness of our algorithm is discussed thanks to a numerical simulation of the polarization encryption/decryption procedure of a 256 gray-level image. Of additional special interest is the immunity of this encryption algorithm to brute force attacks.
