Scientists from Toshiba’s Cambridge Research Laboratory have invented a system capable of generating 100 quantum keys every second, each consisting of 128 bits. This is fast enough for every individual frame of video to be protected by its own encryption. http://www.nature.com/news/2005/050425/full/050425-9.html
