| abstract | A cryptographic processing system 10 that performs a cryptographic process using a base Bt and a base B * t for each integer t of t = 1, ..., L + 1 (where L is an integer equal to or greater than 1) , the cryptographic processing system comprising: an encryption device (200) that generates, as a ctiphertext ct, a vector in which the attribute information x → t is incorporated in a base vector of the base Bt for at least minus some integer t from t = 1, ..., L; a decryption device (300) that uses, as a decryption key skL, a vector in which the predicate information v → t is embedded in a basis vector of the basis B * t for each integer t of t = 1, ..., L, performs a pairing operation on the cipher text ct generated by the cipher device and the decryption key skL, and decrypts the ciphertext ct; and a key delegation device (400) that generates a lower level decryption key skL + 1 from the decryption key skL, based on a vector in which the predicate information v → L + 1 is embedded in a base vector of a base B * L + 1 and to the decryption key skL used by the decryption device. |
