| Abstract(in English) | We propose a black-box traitor revocable broadcast encryption scheme. This is a variant of a broadcast encryption schemes that, a tracer can identify traitors by black-box accessing a given pirated decoder and to revoke traitors so identified. The size of each of its private keys is constant, the size of the public key is proportional to the number of receivers, and the sizes of its ciphertexts are sub-linear with respect to the number of receivers. Our encryption procedure requires only a public key while its tracing procedure requires a secret key. |
