  • Publication number: 20220286280
    Abstract: Provided is an encryption system that suppresses a communication cost from a key issuing system to a user and controls input to a function in the unit of data. The encryption system includes an encrypting apparatus, a signature apparatus, and a security execution apparatus. The encrypting apparatus generates pseudo-random numbers different for respective pieces of data, and encrypts the generated pseudo-random numbers together with the pieces of data. The signature apparatus regenerates the pseudo-random numbers used by the encrypting apparatus for encrypting the respective pieces of data, and generates control information for certifying validity of the pieces of the data from the regenerated pseudo-random numbers.

  • Publication number: 20220245722
    Abstract: In order to provide an electronic trading system contributing to providing fair trading, an electronic trading system includes a plurality of management servers, a participant terminal, and a trading management server. The plurality of management servers provide a first electronic bulletin board. The participant terminal writes bid data in the first electronic bulletin board. The trading management server acquires the written bid data, and uses the acquired bid data to execute trading through Zaraba method. The trading management server generates a public key and a private key. The participant terminal uses the public key generated by the trading management server to encrypt the bid data. The trading management server uses the private key to decrypt the encrypted bid data.

  • Publication number: 20220237320
    Abstract: A management apparatus is operated by one operating entity. The management apparatus includes: a storage unit that stores a policy information, which is associated with data provided by a data provider to another operating entity that is different from the one operating entity, and which defines a provision permission policy of the data provider for the data; an acquisition unit that refers to a log information in which a first hash value of one policy information is recorded and that obtains a policy information corresponding to the one policy information from the storage unit, the one policy information being associated with one data provided to a data user from the another operating entity; and a comparison unit that calculates a second hash value of the obtained policy information and that compares it with the first hash value.
