A configuration method of an optical signal, an encryption device, and an encryption system makes it possible for a legitimate communicating party to ensure information-theoretic security against a known plain text attack and to communicate long-distance. By adding a transmission information data sequence randomization device to the Yuen encrypted communications device according to the present information, which divides transmission information data into blocks, appends sequence numbers thereto, randomly switches the sequence of the blocks with a digitized signal of output of an electrical noise generator, and inputs same into a transmission data generator of a conventional Yuen encrypted optical transmitter, the relation between a known transmission information data sequence (plain text) and an optical signal which is outputted from the transmitter is randomized, allowing forcibly making even a circumstance wherein a known-plain text attack would be possible into a cipher-text-only attack, realizing information-theoretic security against a known-plain text attack.

An injection flame burner in which temperature of the generated flame itself can be sustained around the flame. A plurality of double structure injection nozzles each consisting of an outer tube and an inner tube provided coaxially with the outer tube, are arranged such that hydrogen gas is ejected from one of the outer tubes and the inner tubes and oxygen gas is ejected from the other tubes, and the injection port of each injection nozzle is located on the injection surface. Each injection nozzle includes at least one main injection nozzle having an inner tube formed to spread toward the injection surface side, another sub-injection nozzle arranged around the main injection nozzle, wherein gas is injected from the inner tube of the main injection nozzle under a higher pressure state as compared with gas injected from the sub-injection nozzle.

A dynamic range of intensity modulation is set to range from a maximum intensity Smax to a minimum intensity Smin. A difference Δ(=Smax−Smin) between the maximum intensity Smax and the minimum intensity Smin is divided by the number 2M of multilevel signals. Thus, a distance (an intensity difference) between adjacent signals is [Δ/2M]. The number 2M of multilevel signals is selected such that the distance [Δ/2M] between adjacent multilevel signals (between an intensity Si and an intensity Si+1) is sufficiently buried within a range of quantum fluctuations obtained when heterodyne measurements are made or buried within a range of quantum shot noise obtained when a direct detection is made. Bases of a basis group are each positioned for intensity signals so as to have a high intensity and a low intensity between which a distance is set to be a certain value smaller than a middle point intensity [Δ/2]. Note that adjacent bases are set to have an intensity signal transmitting a logical value “1” of transmission data and an intensity signal transmitting a logical value “0” of transmission data in an inverted manner.
