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： An encrypted ID takes as its initial value a tag ID that constitutes an original ID of a wireless tag, and is encrypted using an encryption key each time an ID inquiry is received from a reader/writer. Another encrypted ID also takes the tag ID as its initial value, and is encrypted using an encryption key each time an ID inquiry is received. The wireless tag gives confidential variability to the ID by transmitting a combination of the encrypted ID and the another encrypted ID in reply. The reader/writer can obtain the original ID merely by decoding the two encrypted values until they match, and the decoding load does not increase even if the number of wireless tags that are reading targets increases.

摘要： 401 stores, in 302, key d′ obtained by subtracting random number 2r held in 201 from key d held in 105. When an operation starts, the values “−C” and “−C2” are calculated respectively, and the resultant values are stored in a multiplication table memory 205 together with value “C”. In a first operation cycle, 107 selects and outputs an intermediate value 108 held in an in-operation data register 103, and thereby makes a modular-multiplication operation circuit 104 perform squaring. In the second operation cycle, 107 selects and outputs one of three values held in 205 in accordance with the combination of key bit value d′i and random number bit value ri, and thereby makes the modular-multiplication operation circuit 104 perform multiplication. Thereby, a cryptographic processing device that requires a short operation time period, small circuit scale, and has sufficient security can be realized.
摘要翻译： 401在302中存储通过从保持在105中的密钥d减去在201中保留的随机数2r获得的密钥d'。当操作开始时，分别计算值“-C”和“-C2”，并且得到的值为与值“C”一起存储在乘法表存储器205中。在第一操作周期中，107选择并输出保持在工作数据寄存器103中的中间值108，从而使得乘法运算电路104进行平方。在第二操作周期中，107根据密钥位值d i和随机数位值ri的组合来选择并输出保持在205中的三个值之一，从而使乘法运算电路104进行乘法运算。因此，可以实现需要短操作时间段，小电路规模并且具有足够安全性的密码处理装置。

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.
