ABSTRACT:
Provided are a method of configuring a hierarchical network of user groups and resource groups, and a key distribution center. The method includes the steps of: analyzing hierarchical connection relationships between respective user groups and respective resource groups, comparing redundancy rates of the respective hierarchical connection relationships, and determining a connection mode having a larger redundancy rate; separating the respective user groups and resource groups and hierarchically connecting the user groups with the resource groups, according to the determined connection mode; comparing hierarchical connections between the respective separated user groups and resource groups, and removing an overlapping hierarchical connection; and recombining the separate hierarchical connections except for the overlapping hierarchical connection, and configuring an entire network.
