Abstract (in Japanese) (See Japanese page) 
(in English) The differential phase-shift quantum key distribition protocol uses phase differences between adjasent optical pulses as signals. In this article, we propose a modified version of this protocol where not only adjasent optical pulses but also all pairs of optical pulses in a block of pulses are subjected to the detection of phase difference. We show that the security of this protocol can be established without monitoring disturbance in the signals.
