Demonstration of 2.5 Gbit/sec free space optical communication by using Y-00 cipher: toward secure aviation systems

Wireless communication of aviation contains high capacity confidential information and therefore such communication requires secure high speed data communication scheme by using reliable cipher. In this report, the authors propose free space optical communication by utilizing optical intensity-modulated Y-00 cipher for applications of secure aviation systems including unmanned aircraft systems. Y-00 cipher transmitter and receiver with intensity levels of 4096 at data rate of 2.5 Gbit/s are fabricated for secure free space optical communication and a free space Y-00 cipher transmission is experimentally demonstrated.
