Abstract
This paper proposes an application of quantum stream cipher by Yuen-2000 protocol (Y-00) to transmission of High Definition Television(HDTV) and super HDTV signals. First, we summarize several adhoc strengthening methods of security which may provide provable security under individual quantum measurement. Y-00 with the modifications has a provable practical security for HDTV transmission system in which one never needs the change of the seed key forever. Second, we give a brief report on a demonstration of quantum stream cipher by the basic Y-00 of 2.4 Gbps in a real commercial optical network of 196 km by Hitachi Inform.and Commun.Eng. And how to improve it to 10 Gbps system with provable security is discussed, which is a national project of NICT. Finally, design parameters for its application to HDTV(1.48 Gbps) and super HDTV(24 Gbps) of 4320 scanning lines and 60 frame/sec are clarified.
