Title: Throwaway signature method
Inventor: ANZAI JUN
IPC: G09C1/00
Filed: 2000-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a throwaway signature method which has a simple structure and is speedy at signature and verification. SOLUTION: A signature method is configured by using only a simple and speedy unidirectional hash function without a trapdoor. A secret key is defined as x. A public key is defined as y and Y (=h-(x)) (here, hy(x) is described as h-y(x)). A signer 1 calculates a signature S=h-(y-m)(x) from a message m (<y) and transmits it with the message to a verifier 3. The verifier 3 confirms that Y=h-m(S) holds. Since m' to be signed next is restricted by (Y-m')<(y-m), it is a throwaway signature. To extend the life of the public key, m is gradually enlarged by padding. To speed up a signature, if m<<y, the signature is defined as S=h-m(x), and the verification is defined as Y= h-(y-m)(S).

Title: Power circuit
Inventor: DOI SHINICHI
IPC: H02M3/155
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To solve a problem that an element is broken by an overvoltage during the time from a release of a load to an ON-OFF interruption of a transistor T1. SOLUTION: When a load is released, an applied voltage one terminal of a resistor R2 drops near to a reference potential. A PWM control circuit 12 so controls the transistor T1 as to raise the applied voltage. Then, a terminal voltage of an output terminal S1 exceeds 27 V, a Zener diode ZD1 becomes conductive and the applied voltage of the other terminal of the resistor R2 is raised. The PWM control circuit 12 controls an ON-OFF ratio of the transistor T1 corresponding to the raised applied voltage and, as a result, the applied voltage of the output terminal S1 is stabilized. On the other hand, an applied voltage of an output terminal S2 falls lower than the a reference voltage V2 when the load is released. Then, a RS-FF circuit 14 forcibly interrupts ON-OFF of the transistor T1. Here, a response speed of the PWM control circuit 12 is faster than that of the RS-FF circuit 14.
