摘要： Disclosed is a digital document management program capable of achieving a third-party certification of document information with reduced amount of meta data.At the registration time of new document information, the digital document management program manages a digital signature created in association with document information. At the correction time of the document information, the program acquires partial identification information related to a corrected part of the document information before correction, creates a digital signature to be appended to the corrected document information, and manages the digital signature and partial identification information related to the corrected part of the document information in association with the corrected document information. At the verification time, the program uses partial identification information, the partial identification information corresponding to a corrected part of the document information before correction, and digital signature to perform verification.

摘要： REDC (A*B) is calculated for the values A and B by using a Montgomery's algorithm REDC. The part related to the A*B is performed by the three-input two-output product-sum calculation circuit. One digit ai of the value A, one digit bj of the value B and a carry value c1 are input to the product-sum calculation circuit, and ai*bj+c1 is calculated thereat. The higher-order digit of the r-adic two-digit of the calculation result is used as the carry value c1, and the lower digit is used for a later calculation. Further, one digit ni of a modulo N for the REDC, a predetermined value m and a carry value c2 are input into the product-sum calculation circuit, and n*ni+c2 is calculated thereat. The higher-order digit is used as the carry value c2, and the lower digit is used for a later calculation.

摘要： In verifying a digital document, an input of a digital document is received and the digital document is divided into arbitrary constituent parts. A normal random number or a pseudo random number is assigned to each of the constituent parts according to the order in which the constituent parts appear in the digital document. Thus, verification of the authenticity of a digital document is enabled even when an alteration, such as a change of the order of the partial documents or a copy thereof, has been made to the digital document.

摘要： The first route selection device re-arrays a plurality of extended key mask values at random according to the value of a random number generated by a random number generation device. An extended key operation device generates an exclusive logical OR of a plurality of the re-arrayed extended key mask values, a data string representing extended key and an input data string. The second route selection device re-arrays the data string of the exclusive logical OR by performing a re-array conversely with the first route selection device according to the value of the random number. A non-linear conversion device applies non-linear conversion to the re-arrayed data string and outputs a data string masked by a plurality of non-linear conversion mask values. The third route selection device re-arrays the masked data string by performing the same re-array as the first route selection device according to the value of the random number.

摘要： An information access system comprises a reader/writer for continually transmitting an ID request signal at a first frequency and being continuously ready to receive an RF signal at a second frequency, and an active contactless information storage device having a receiver for sensing a carrier of an RF signal at the first frequency, and a transmitter for transmitting a response signal at the second frequency when the ID request signal is received. When the receiver senses a carrier of an RF signal at the first frequency in a particular predetermined period, the receiver receives further the ID request signal, and, in response to the ID request signal, the transmitter transmits a response signal at the second frequency carrying an ID of the storage device stored. In the carrier sensing, the controller causes the receiver to be in an active state and the transmitter to be in an inactive state in the predetermined periods. When the receiver attempts to sense a carrier of the RF signal at the first frequency in a particular predetermined period but detects no carrier, the controller controls the receiver and the transmitter to maintain the inactive state during a sleep period between the particular predetermined period and the subsequent predetermined period.

摘要： A therapeutic agent and a treatment method for uremia of human and animals, which therapeutic agent can be easily taken, has lower side effects, and which is not expensive in view of medical economics, are disclosed. The therapeutic agent for uremia in patients suffering from chronic renal failure comprises as an effective ingredient a prostaglandin I2 derivative having a specific structure, such as beraprost sodium. The therapeutic agent for uremia ameliorates the uremia concurred in patients with chronic renal failure without accompanying side effects, and restoration of decreased appetite, improvements in activities, increase in body weight and the like are achieved. The therapeutic effect of uremia is clear alleviation or disappearance of symptoms of uremia grasped as clinical symptoms, observed in the state of renal failure, especially even in spite of the state wherein the decrease in renal function is progressed.
