Abstract: The transistor includes a semiconductor substrate, e.g. of silicon, with a buried collector and having an oxide film with a conductive, thin-film base electrode formed on the substrate one after another. The substrate is provided with a heterojunction of e.g. Si or SiGe Ge. The collector is surrounded by the conductive thin film and is formed in transistor active region, bounded by patterns of the conductive thin and first oxide films on the buried collector on both sides of the conductive thin film is formed a first spacing layer. A multilayer base is formed in the active region, while an emitter is grown selectively on the base in an emitter region, bounded by etching of a second oxide film, on whose both sides is formed a second spacing layer. The emitter carries an electrode, while a passivating insulation layer is formed on the structure surface. Metal coupling lines are formed on the base, emitter, and buried collector and go back through the insulation passivation layer and/or the two oxide layers.

Abstract: An identification scheme, a digital signature scheme giving message recovery, and a digital signature scheme with appendix are disclosed. In processing and transmitting information, a transmitting counterpart of a transmission message is confirmed. The unauthorized modification of the message is confirmed and transmitting behavior is detected, thereby providing the reliable information service.

Abstract: A modulo reduction method using a precomputed table to increase a reduction speed during the execution of ordinary operational processes using computers and comprises a first step which searches out with an index of an upper log2t (t>/=1) bit number and adds the value stored in a table to a lower n(n>/=512) bit number; a second step, which if the result, obtained from the addition of said lower n bit number to the number searched out from the table at said first step, produces an overflow (1 bit), eliminates said overflow and finishes the execution of an operation; and a third step, which if said overlow does not occur at said second step, adds N on a modulo N to the result obtained from said first step and finishes the execution of the operation.

Abstract: An identification scheme which allows a prover to identify his own identity to a verifier more certainly and prevents already used authentication information from being re-used, a key exchange which uses a common secret key between two users in order not to allow an unauthorized to find it out, a digital signature scheme giving message recovery and digital signature scheme with appendix for producing a digital signature of a message recovery type or appendix type according to the size of a message to be signed, a multi-digital signature scheme for allowing multiple signers to generate digital signatures with respect to the same message and producing them in a message recovery type or appendix type according to the length of the message to be signed, and a blind digital signature scheme for producing a digital signature when a message to be signed should not be opened to the public as well as the signer and therefore a signer does not know the contents thereof.

Abstract: The method involves the authenticating partner choosing a number r and using three coefficients g, q and p to obtain a mathematical equation x. The equation number, together with the identity, I, is sent as authentication. A verifier signal (y) is generated by forming a mathematical function and using the value q. A secret key is then added to form the output verifier. The receiver investigates the values of the authentication and verification numbers. The secret key is then recovered and compared with the sender identity, to authenticate the information received.

Abstract: The system is initialised by selecting a modulo n under certain constraints, and two other numbers generated using modulo n arithmetic to form a triplet. A primitive element (b) is selected for modulo (f), satisfying b (mod n)=1. The pair (b,f) are combined with the triplet of the previous stage to form public keys. Two secret keys (p' and q') are selected. Verification information is computed from this combination of values and a random number in the range 0 to f-1 is processed with the same information. The signature includes this random number.
