Abstract:
A method and a system for managing a key of a home device in a broadcast encryption system are provided. A hierarchical structure of a group set comprising a plurality of nodes corresponding to the home server and a plurality of nodes corresponding to the home device is formed. A key set to be allotted to the node set is generated. The node group is allowed to correspond to the key set to generate key-node corresponding information according to a request of the home server.
