Title: Validation system for electronic transaction
Inventor: NAGAI YASUHIKO
IPC: G09C1/00
Filed: 1987-07-24
Abstract: PURPOSE: To realize the high-speed efficient processing on operation by using a public key for deciphering whose length is shorter than that of an encipherment secret key in an electronic transaction authentication system using a public key encipherment system. CONSTITUTION: In the processing system where documents are substituted for electric information to perform electronic transactions, data indicating contents of a transaction text is enciphered by the public key encipherment system to generate authentication data. Enciphered authentication data is deciphered by the public key for deciphering to confirm the authentication data. At this time, a public key whose length is longer than that of the encipherment secret key is adopted as the public key for deciphering. A high-speed remainder calculation system using a remainder table is adopted to generate the authentication data. A conventional system where a quotient is obtained and is subtracted from a dividend is adopted to generate the authentication data.  Consequently, the speed of the confirmation processing of authentication data is increased because the length of the public key for deciphering is longer than that of the encipherment secret key.

Title: Data recording device and data recording method as well as data reproducing device and data reproducing method
Inventor: AMANO MITSUYASU
IPC: G11B20/10
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to effectively utilize the memory capacity of a tape by intermittently reading out data from a memory means in such a manner that the moment data rate of the prescribed data is determined as a first data rate and the average data rate of the data as a second data rate. SOLUTION: The accumulated digital data quantity of a memory section is changed to a saw tooth form by the intermittent operations of a data reproducing device. The data reproducing device continuously reads out the digital data at the second data rate from the memory section and executes the intermittent reproduction to alternately repeat the reproducing from a memory medium and the pause of the reproducing. Then, the first data rate is higher than the second data rate. The first data rate is converted into the second data rate suitable for various kinds of external apparatus by a data rate conversion section, by which the output by the external apparatuses having the second data rate different from the data rate to the memory medium of the data reproducing device is made possible.
