    摘要: A user key allocation method for broadcast encryption is provided. The user key allocation method includes generating a plurality of subsets by dividing one group including a plurality of nodes to sub-groups and allocating key sets with respect to the subsets, respectively. The nodes included in the subset may be odd nodes and even nodes of the nodes of the group. The nodes are arranged so that privileged nodes are consecutive or there is only one privileged node. Accordingly, it is possible to reduce the data size transmitted from the server to the nodes by constituting one or more subsets from the nodes consecutively arranged and providing key sets with respect to the subsets.
