Abstract

See full text

An information output apparatus identifies, according to a rule established for each of functional encryption protocols or a rule established for each combination of the protocols, one or more identifiers corresponding to a particular functional encryption protocol or a combination of the particular protocols, sets a particular piece of first correspondence information corresponding to the identifier or identifiers, and outputs first information which is a ciphertext or key information of the functional encryption scheme that corresponds to the particular piece of first correspondence information. An information processing apparatus inputs the first information and second information which is key information or a ciphertext of the functional encryption scheme that corresponds to a particular piece of second correspondence information into a decryption function of the functional encryption scheme and, when the truth value of a logical formula corresponding to the combination of the particular piece of first correspondence information corresponding to the first information and the particular piece of second correspondence information corresponding to the second information is true, generates a decryption result.
