    "abstract": "In this paper, we present an efficient implementation method of physical\nlayer of Y-00 which can support a secure communication and a quantum key\ndistribution (more generally key expansion) by IMDD(intensity modulation/direct\ndetection) or FSK(frequency shift keying)optical fiber communication network.\nAlthough the general proof of the security is not yet given, a brief sketch of\nsecurity analysis is shown, which involve an entanglement attack.",
