New Scientist reported that Japanese scientists developed a method of encrypting messages using quasars. Quasars, thought to have been powered by matter accreted onto blackholes, emit strong radio waves. Scientists from Japan's National Institute of Information and Communications Technology propose of using the quasar's radio signals as a source of randomness for encrypting messages, much like one-time pads. Two parties will only have to agree on which quasar to utilize, and use that quasar's radio signals to add randomness to the cipher.
