ABSTRACT
This article reports that a technique for 'hiding' information within broadband light could provide a cheaper and faster alternative to quantum encryption. Andy Harvey, senior lecturer at Heriot-Watt University's school of engineering and physical sciences, has developed a method for optically encrypting information, and is talking to fibreoptics and secure communications companies about commercialising the technology. The technology also allows secure data to be sent across long distances. However, if the signal is put through a decryptor, which contains a matching optical key, the information can be retrieved.
