    摘要: In a signature creating apparatus, a clock generates a time stamp and in which time can be set only by a computer installed in a certificate authority center. Further, connecting sections connects an apparatus ID for specifying an apparatus and the time stamp and personal identification information for identifying an implementor to a plain-text so as to create data for the signature. A signature creating circuit encrypts the data for the signature using a signature creating key or the like and generates the signature. A connecting section connects the signature to the data for the signature and transmits the data as data after signature.

    摘要: When a user works data required for allowance for the use thereof, the work processing is carried out by utilizing an exclusive work processing device. Thereafter, only the data of work information indicating what kind of working has been made to the original data (for example, differential static image data indicating a difference between the original static image required for allowance for the use and the static image after having been worked) is stored, whereby the use without permission of the data is prevented.

    摘要: A file protection system for protecting a file which is stored in a storage unit includes a storage position deciding unit for deciding a positional-information corresponding to an area in which information of the file is stored in the storage unit and an encryption unit for encrypting the information of the file in accordance with a predetermined algorithm using at least a part of the positional-information decided by the storage position deciding unit. Information obtained by the encryption unit is stored in the area identified by the positional-information in the storage unit. A file protection system is operable when information of a file which was encrypted as described above is read out from a storage unit. The file protection system includes a decryption unit for decrypting the encrypted information of the file which is read out from an area in the storage unit using information corresponding the area, an extracting unit for extracting the positional-information from information obtained by the decryption unit, and a determination unit for determining whether or not the positional-information extracted by the extracting unit is equal to corresponding positional-information which is at least a part of the information corresponding to the area from which the encrypted information of the file is read out. When the determination unit determines that two pieces of positional-information are not equal to each other, it is determined that the information obtained by the decryption unit does not include correct information of the file.

    摘要: The base plate is transmissive to terahertz waves, and a sample is disposed at the base plate. In the conductive periodic structure, plural transmission portions that transmit terahertz waves are arrayed with a predetermined period. The conductive periodic structure is disposed apart from a position at which the sample is disposed. The waveguide includes a total reflection surface provided at a boundary face with the conductive periodic structure. The total reflection surface totally reflects incident terahertz waves, and the waveguide guides incident terahertz waves toward the total reflection surface. The magnitudes of one or more of a distance between the position at which the sample is disposed and the conductive periodic structure, a property of the base plate, and the predetermined period are set such that a dip showing a characteristic absorption is formed in a predetermined frequency region of a spectrum of terahertz waves.

    摘要: A memory management unit manages a memory that stores a code, and sets that the memory that stores the code to be executed is valid to make a processor execute the code stores a verification key used to verify a validity of the code in a verification-key storing unit. When the code is stored in the memory and ready to be executed by the processor, the memory management unit verifies the validity of the code using the verification key stored in the verification-key storing unit and verification information assigned to the code. The memory management unit controls to set that the memory is valid when the validity is verified by the verifying unit, and not to set that the memory is valid when the validity is not verified by the verifying unit.
