摘要： The present invention enables deniable zero-knowledge interactive proof to be performed with low amounts of communications and calculations by utilizing a method of a special honest verifier zero-knowledge interactive proof when such method is given. The verification apparatus generates a commitment of a challenge value with respect to a predetermined relationship and transmits the commitment of the challenge value to the proving apparatus, which determines whether or not a required relationship using the commitment of the challenge value holds, and stops its operation if such relationship does not hold. The proving apparatus causes the proof commitment generation apparatus to generate a proof commitment and transmits the proof commitment to the verification apparatus, which transmits a challenge value and a random number to the proving apparatus. The ladder transmits a response to the verification apparatus which determines acceptance or non-acceptance of the proof through communications with the interactive proof verification apparatus.

摘要： A weakly computational zero-knowledge proof class is a relaxed zero-knowledge proof class and is based on a fact that any zero-knowledge proof yields nothing beyond necessary information but a proof system that yields nothing beyond necessary information is not always the zero-knowledge proof. It is ensured that a proof system under a class broader than the zero-knowledge proof class yields nothing beyond necessary information. If it is not included in the zero-knowledge proof class but prevents leakage of information, such a proof system can achieve a higher possibility of designing effective cryptography protocols.

摘要： A signature device 2 creates encrypted data by encrypting a first element of a member certificate through use of a first random number and public information disclosed by said group management device 1. The signature device 2 also creates first and second converted data by converting the first element through use of a random number and public information. The signature device 2 further creates knowledge signature data from which information concerning the first element, the second element, and the signature key will not be divulged, and outputs a group signature which contains the knowledge signature data together with a message. A verification device 3 verifies whether a group signature has been created by using a member certificate of one of the registered members in the group and a signature key, based on the message, the group signature, and the public information.

摘要： A single crystal ingot is cut to an axial direction so as to including the central axis, a sample for measurement including regions [V], [Pv], [Pi] and [I] is prepared, and a first sample and second sample are prepared by dividing the sample into two so as to be symmetrical against the central axis. A first transition metal is metal-stained on the surface of the first sample and a second transition metal different from the first transition metal is metal-stained on the surface of the second sample. The first and second samples stained with the metals are thermally treated and the first and second transition metals are diffused into the inside of the samples. Recombination lifetimes in the whole of the first and second samples are respectively measured, and the vertical measurement of the first sample is overlapped on the vertical measurement of the second sample. The boundary between the regions [Pi] and [I] and the boundary between the regions [V] and [Pv] are respectively specified from the overlapped result.

摘要： An ingot is manufactured by pulling it up such that V/Ga and V/Gb become 0.23 to 0.50 mm2/minute ° C., respectively, where V (mm/minute) is a pulling-up speed, and Ga (° C./mm) is and axial temperature gradient at the center of the ingot and Gb (° C./mm) is an axial temperature gradient at the edge of the ingot at temperatures in a range of 1,300° C. to a melting pointy of silicon. A wafer obtained by slicing the ingot is heat treated in a reductive atmosphere at temperature in a renge of 1,050° C. to 1,220° C. for 30 to 150 minutes. A silicon wafer free of OSF's, free of COP's, and substantially free of contamination such as Fe and of occurence of slip, is obtained.

摘要： A method of manufacturing a sealed-type storage battery using a hydrogen-occlusion electrode and an alloy for making the electrode is described. The sealed-type storage battery uses the hydrogen-occlusion electrode as a negative electrode. The battery is filled up with an alkaline electrolyte and is then allowed to stand for not more than 14 hours prior to the commencement of the initial charging of the battery. The initial charging is discontinued for at least one hour when the battery is in an incomplete charged state, i.e., when the battery is charged 5% or more but less than 100% of its rated capacity. Thereafter, the charging of the battery is continued until the battery is charged to its full capacity. The invention provides a sealed-type storage battery which has a low internal pressure during an overcharging operation, has a small capacity loss when operated whether at a high or low temperature, and has a longer cycle life as compared to conventional batteries.

摘要： A distance between a radiation source and a detector is first set to a first distance and the number of pulses of a .gamma.-ray is detected. Then, the distance between the radiation source and the detector is set to a second distance different from the first distance and the number of .gamma.-ray pulses is detected. A density .rho. of a sample is finally calculated on the basis of a ratio of the two detection pulse numbers which were detected. The radiation source is set on the surface of the sample or in the sample. The sample detector is set on the sample surface. Fundamentally, one radiation source and two detectors are used. In the case of using one radiation source and one detector, either one of them is moved and the number of pulses is detected twice.
