    "abstract": "We give a Shor-Preskill type security-proof to the quantum key distribution\nwithout public announcement of bases [W.Y. Hwang et al., Phys. Lett. A 244, 489\n(1998)]. First, we modify the Lo-Chau protocol once more so that it finally\nreduces to the quantum key distribution without public announcement of bases.\nThen we show how we can estimate the error rate in the code bits based on that\nin the checked bits in the proposed protocol, that is the central point of the\nproof. We discuss the problem of imperfect sources and that of large deviation\nin the error rate distributions. We discuss when the bases sequence must be\ndiscarded.",
