Abstract: an encryption unit () that an encryption apparatus () includes, when a user secret key sk� is generated using a secret key msk of attribute based encryption and a set of attributes � corresponding to a decryption-possible condition l, generates a key k and a ciphertext p corresponding to the key k by encrypting the decryption-possible condition l using, as an encryption key of the attribute based encryption, a key pk consisting of a public key mpk corresponding to the secret key msk and a public key pqcpk of post quantum cryptography, regards a part of the ciphertext p where the decryption-possible condition l is encrypted based on a secret value as p-d, regards a part of the ciphertext p where the secret value that is shared is encrypted as p-ss, and generates k′ and p′-d by randomizing each of the key k and the p-d using a random number r, and generates a ciphertext c by encrypting data consisting of the p-d and the random number r using the public key pqcpk. here, the p-ss, the p′-d, and the k′ are decryption-possible verification parameters corresponding to the user secret key sk�.
