DNA Encoding-Based Optical Image Encryption

Optical beams with helical wavefronts, carrying orbital angular momentum, have become a hot topic for research due to their inherent feature such as an infinite number of orthogonal modes. An idea of optical image encryption based on deoxyribonucleic acid encoding and an optical vortex beam is proposed that provides a new way of encoding information into optical vortices without compromising the security of the optical cryptosystem.
