摘要：An efficient key generating method that uses recursive hash chains is proposed for hierarchical access control. The proposed method introduces recursive hash chains for reducing the number of managed keys. In addition to decreasing this number down to one, regardless of the number of the controlled targets and their depth, the number of keys delivered to a user by using the proposed method is equal to or less than that in conventional methods.
