| Abstract(in English) | This paper studies a new concept of access control which is referred to as hierarchical access control. A hierar-chical access control method not only controls access to existing secret information but also controls access to new secret information derived from existing secret information. Secure computation on existing secret information produces new secret information, whereas the computation keeps existing secret information secure. In addition, different access control rules are applied to existing secret information and to new computed secret information, whereas conventional access control with secure computation controls access to both information by only one rule. The proposed hierarchical access control method is based on (k, n)-threshold secret sharing. |
