In current content delivery service, contents are usually encrypted for access control mechanism, so several key distribution schemes have been proposed. In this paper, we propose a new key derivation scheme for hierarchy-based access control. We assume that content consumers are listed in digraph structure, and all nodes are assigned seeds(prekeys) for decryption keys. All decryption keys are generated from initial keys assigned in root nodes, and a decryption key is derived from seeds of an ancestor node only using the one-way hash function. The proposed scheme includes conventional hierarchy-based key derivation schemes and can be implemented with low cost in computation for decryption keys because we do not need exponential calculations.

“…This proposed method can reduce both the amount of the initial master keys and the amount of key generating calculation by the pruning method. We believe that our proposal can be fundamental tools for time-limited access control schemes [18] and group key management schemes [9].…”
