  • Patent number: 10235539
    Abstract: 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.

  • Patent number: 10140460
    Abstract: A data storage system (1) uses an encryption scheme in which an encrypted file can be decrypted using a decryption key when a decryption condition set in the encrypted file is satisfied by a user attribute set in the decryption key. The data storage system (1) stores encrypted files encrypted by the encryption scheme in a file storage apparatus (20). When user attribute is specified from a user terminal (10), the data storage system (1) extracts the encrypted file of which the decryption condition is satisfied by the specified user attribute from among the encrypted files stored in the file storage apparatus (20), and displays the extracted encrypted files classified by decryption condition.

  • Publication number: 20160330022
    Abstract: A cryptographic system (10) uses a cryptographic scheme capable of decrypting ciphertext on which one of two pieces of information corresponding to each other is set, with a decryption key on which the other piece of information is set. A key generation apparatus (401) generates a user private key on which one of key information u and key information y corresponding to each other is set, and a re-encryption key to convert ciphertext which can be decrypted with an attribute private key on which one of user attribute information x and user attribute information v corresponding to each other is set, into a re-ciphertext on which the other of the key information u and the key information y is set. A ciphertext storage apparatus (201) stores ciphertext on which the other of the user attribute information x and the user attribute information v is set. A re-encryption apparatus (301) re-encrypts the ciphertext stored in the ciphertext storage apparatus with the re-encryption key to generate the re-ciphertext.

  • Patent number: RE48146
    Abstract: 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.
