    摘要： A bearing assembly includes an IC tag with information to be reliably exchanged between the IC tag and an external reader/writer, and a rolling bearing including outer and inner races and rolling elements disposed between the outer and inner races. The IC tag communicates with the external reader/writer device without contacting the reader/writer device, is attached to a metal member of the rolling bearing, includes a tag antenna, and is configured so information can be exchanged between the tag antenna and a reader/writer antenna of the reader/writer device by forming a closed magnetic circuit between the tag antenna and the reader/writer antenna. The IC tag is received in a hole in a metal member surface. The tag antenna includes at least two protrusions facing the opening of the hole and arranged so magnetic fluxes leaving/entering the protrusions pass inside the edge defining the hole opening and extend outside the hole.

    摘要： A searchable encryption resistant to frequency analysis. A conversion rule management device generates a conversion rule table associating a search keyword with a conversion keyword group. Based on the conversion rule table, a data registration device generates registration data associating encrypted data with an encrypted keyword, and registers the registration data in a server device. An information processing device obtains from the conversion rule table a conversion keyword group associated with a specified search keyword, generates an encrypted keyword group, and requests a data search by specifying the encrypted keyword group. Using as a search key an encrypted keyword included in the encrypted keyword group, the server device searches for encrypted data associated with the search key, and returns searched encrypted data. The information processing device decrypts the searched encrypted data, and outputs as a search result search data obtained by decryption.

    摘要： A data search server stores a system ciphertext including a data ciphertext and a keyword ciphertext in each category-specific DB unit for each data category, and stores each category-determination secret key being associated with each category-specific DB unit. A search request receiving unit receives from a data search terminal a search request including a search trapdoor and an index tag. A data searching unit searches for a category-determination secret key with which the index tag is decrypted to the same value as a key-determination value. Using the search trapdoor, the data searching unit performs a search of a Public-key Encryption with Keyword Search scheme on system ciphertexts in a category-specific DB unit associated with this category-determination secret key. A search result transmitting unit transmits to the data search terminal a data ciphertext included in a system ciphertext which has been found as a hit in the search.

    摘要： In a wildcard-applicable anonymous hierarchical identity-based encryption system, it is aimed to make the number of pairing operations a fixed number. A user identifier ID and a pattern P are used. The user identifier ID includes k number of hierarchy identifiers. The pattern P includes either of a hierarchy identifier, a wildcard value and a blank value for each hierarchy. An encryption device 400 extracts a key value H corresponding to a hierarchy of the wildcard value and a key value H corresponding to a hierarchy of a pattern value from a public key PK, calculates a cipher value C1 and a cipher value C3, and outputs ciphertext data CT including plaintext cipher value C0, the cipher value C1, and the cipher value C3. A decryption device 300 extracts the hierarchy identifier of the hierarchy corresponding to the wildcard value from the user identifier ID, decrypts the plaintext cipher value C0 included in the ciphertext data CT using the extracted hierarchy identifier, the cipher value C1 and the cipher value C3 which are included in the ciphertext data CT, and outputs plaintext data M.
