The revoked node groups are node groups consisting of only revoked nodes, and the independent revoked nodes are revoked nodes not belonging to any of the revoked node groups. Then, encrypted content keys are obtained by encrypting content keys using broadcast encryption, by using an encryption key set that has a form that cannot be generated using a decryption key set that the revoked nodes possess, and a set of encrypted content keys is generated. Thereafter, the revoke information and the set of the encrypted content keys are transmitted to all of the nodes arranged in the hierarchical structure. | 2009-11-05 |
