Optical Encryption Techniques: An Overview
Mohamed A. Mohamed, A. S. Samarah, M. I. Fath Allah · 2014
Over the years extensive studies have been carried out to apply coherent optical methods in real time communications and multimedia transmission. This is especially true when a large amount of information needs to be processed. The transmitted data can be intercepted by non-authorized people; this explains why considerable effort is being devoted at the current time to data encryption and secure transmission. In this paper, a literature survey of the performance and methodology of some recent optical encryption techniques will be presented. These techniques have been applied on different applications.
