    摘要: A medication history management apparatus enables a person to check for side-effects caused by combinations of drugs, and duplicated administration of drugs, when purchasing non-prescription drugs, even without medical knowledge. The medical history management apparatus securely stores medication history information identifying drugs taken in the past and drugs prescribed in the past in a secure storage unit 403, and stores mutual effect information that shows side-effects caused by combinations of drugs. The medical history management apparatus receives input information identifying a drug from a keypad, judges whether the set of the input information and the any of the drug history information match the any of the mutual effect information, and outputs a judgment result.

    摘要: A recording/playback apparatus is capable of using pre-image-converted content in a case of transferring an image-converted content to another device, then back from transfer-destination device to the recording/playback apparatus. The recording/playback apparatus includes a storage unit that stores a first encrypted content generated by encrypting the content, a second encrypted content generated by performing an irreversible compression to convert the content, thereby obtaining a converted content, and by encrypting the converted content, and a content key for decryption of the first and second encrypted contents, a key transfer unit that writes the content key to the external recording medium, and erases the content key stored in the storage unit, and a content transfer unit that, after the content key has been erased, writes the second encrypted content to the external recording medium, and erases the second encrypted content from the storage unit.

    摘要: A recording/reproduction device 10 receives content broadcast from a content provision device 11. The recording/reproduction device 10 encrypts the received content using a device key, to generate first encrypted content. The recording/reproduction device 10 decrypts the first encrypted content to obtain the content, performs an image conversion on the obtained content to generate converted content, and encrypts the converted content using a medium key to generate second encrypted content. The recording/reproduction device 10 writes the second encrypted content, the medium key, and the device key to a portable medium 14. When the portable medium 14 is inserted in a mobile information terminal 15, the mobile information terminal 15 decrypts the second encrypted content using the medium key to obtain the converted content, and reproduces the converted content.

    摘要: A computer system having resistance to timing attacks based on measuring processing times is offered. The computer system encrypts or decrypts a plain text or ciphertext via a process of converting the partial data on the plain text or the encrypted text into conversion data. A conversion table includes one piece of conversion data corresponding to the partial data at the start position of the line table area and includes data not associated with the conversion in the other position. A computer program includes: an operation instruction group for calculating the predetermined position of the corresponding conversion data in the conversion table by using the acquired partial data; and a read instruction group for reading out the conversion data from the position calculated from the conversion table.

    摘要: The data encryption apparatus with a data converting unit splits 256-bit input data into 32-bit data blocks A1, B1, A2, and B2. A first combining unit performs an exclusive OR operation on A1 and B1, and on A2 and B2. A first scramble unit branches A1, A2, and the results of the exclusive OR operations (C1 and C2) into three data blocks each, and for each set of three data blocks, shift-rotates two of the data blocks and combines the shifted data blocks with the remaining data block. A second combining unit performs an exclusive OR operation on D1 and E2, and on D2 and E1, which are the results of the processing performed by the first scramble unit. A block concatenating unit concatenates the results of the operations performed by the second combining unit. A second scramble unit branches the concatenated data into three data blocks, shift-rotates two of the data blocks and combines the two shifted data blocks with the remaining data block.

    摘要: A data encryption apparatus reduces a hardware gate scale over that of conventional technology which uses substitution tables, and realizes high scrambling performance. The data encryption apparatus includes a data converting unit that splits 256-bit input data into 32-bit data blocks A1, B1, A2, and B2. A first combining unit (43) performs an exclusive OR operation on A1 and B1, and on A2 and B2. A first scramble unit (44) branches A1, A2, and the results of the exclusive OR operations (C1 and C2) into three data blocks each, and for each set of three data blocks, shift-rotates two of the data blocks and combines the shifted data blocks with the remaining data block. A second combining unit (45) performs an exclusive OR operation on D1 and E2, and on D2 and E1, which are the results of the processing performed by the first scramble unit (44). A block concatenating unit (46) concatenates the results of the operations performed by the second combining unit (45). A second scramble unit (47) branches the concatenated data into three data blocks, shift-rotates two of the data blocks and combines the two shifted data blocks with the remaining data block.
