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 server device 201 comprises a communication part 231, a search history storage region 213, a data storage part 210, and a checking part 220. The communication part receives a set of a trapdoor and a deterministic encrypted keyword from a search device 401. The search history storage region 213 stores the set of the trapdoor and the deterministic encrypted keyword. The data storage part 210 stores keyword information in which search target data and an encrypted keyword are associated with each other. If the deterministic encrypted keyword is obvious, a deterministic encrypted keyword corresponding to the encrypted keyword is additionally associated with the search target data and the encrypted keyword in the keyword information. The checking part 220 checks whether or not a deterministic encrypted keyword which matches the received deterministic encrypted keyword exists in the search history storage region 213. If the deterministic encrypted keyword exists, the checking part 220 executes a concealed search targeting the data storage part 210, based on a deterministic encryption scheme using the deterministic encrypted keyword existing in the search history storage region 213. If the deterministic encrypted keyword does not exist, the checking part 220 executes the concealed search targeting the data storage part 210, based on a probabilistic encryption scheme using the received trapdoor and the encrypted keyword stored in the data storage part 210.

摘要： An access terminal apparatus provides a group determination key being a decryption key to a data center apparatus previously, and then transmits grouping information generated from a keyword of storage target data and having been encrypted to the data center apparatus, with encrypted data of the storage target data and tag data of the encrypted data of the storage target data. The data center apparatus stores the encrypted data relating it to the tag data, decrypts a part of the grouping information with the group determination key, derives an index value from a bit value obtained by the decryption, and stores the derived index value and the tag data relating them with each other.

摘要： A confidential search that can flexibly control searchable data depending on a role or authority of a user when the data is shared in a group. When the inner product of an attribute vector and a predicate vector is a predetermined value, the confidential search system conducts pairing computation of decrypted data generated based on the attribute vector and a decryption key generated based on the predicate vector, so as to realize confidential search by utilizing an inner-product predicate encryption process that can decrypt the encrypted data. In particular, the confidential search system enables flexible control of searchable data depending on the role or authority of the user, by devising a method of generating the attribute vector and the predicate vector.

摘要： Based on an encrypted feature vector (comparison ciphertext) encrypted with a public key of a decryption apparatus and an encrypted feature vector (target ciphertext) encrypted with the public key of the decryption apparatus, and a random number (temporary key) generated by a random number generation unit (temporary key generation unit), an encrypted random similarity degree calculation unit (interim similarity degree ciphertext calculation unit) performs calculation for calculating a similarity degree in a first stage, with two encrypted feature vectors kept encrypted, thereby calculating a second challenge. The decryption apparatus decrypts the second challenge with a secret key sk of the decryption apparatus, and performs calculation for calculating the similarity degree in a second stage with a result of the decryption kept encrypted with the temporary key, thereby calculating a second response. A plaintext similarity degree extraction unit (similarity degree calculation unit) decrypts the second response with the temporary key, thereby calculating a similarity degree.

摘要： In a secure search system to be used by a plurality of users, the size of a ciphertext is reduced and the need to generate a new ciphertext when a new user is added is eliminated. A public parameter generation device 100 generates a pair of a public parameter and a master secret key. Using the public parameter, an encryption device 400 encrypts a keyword and generates a ciphertext. Using the master secret key, a user secret key generation device 200 generates a user secret key of a query issuing device 300. Using the user secret key, the query issuing device 300 generates a query for searching for the keyword. Based on the ciphertext and the query, a search device 500 determines whether a hit is obtained for searching.

摘要： A tamper resistant apparatus 101 is mounted inside of a PC 900 and stores confidential information A through C. The tamper resistant apparatus 101 receives data from an application 118 which operates on the PC 900, processes the data using the confidential information A through C, and returns processed data to the application 118. To the tamper resistant apparatus 101, plural external sensors 110 provided to the PC 900 are connected. The plural external sensors 110 detect opening/closing of a case of the PC 900 or movement of the body of the PC 900 and send a detection signal to the tamper resistant apparatus 101. On inputting the detection signal from the plural external sensors 110, the tamper resistant apparatus 101 selects and erases confidential information to be erased from the confidential information A through C according to the tamper resistant policy stored previously.
