| Abstract(in English) | In this paper, we present and evaluate the scheme named "Generalized Tree Limited Pattern Division Scheme" which generalized [1]. This scheme is one of the tree-based key management systems for digital content protection. In [1], "Node Revocation Pattern (NRP)" is defined, and the device keys are assigned to every possible patterns of NRP for each node. In the present scheme, we generalize [1] by assigning device keys to a subset of possible patterns of NRP. |
