An efficient key assignment scheme for access control in a large leaf class hierarchy
چکیده انگلیسی

The employees of an organization are usually divided into different security classes to authorize the information retrieval, and the number of leaf classes is substantially larger than the number of non-leaf classes. Additionally, the alternations in leaf classes are more frequent than in non-leaf classes. We proposed a new key assignment scheme for controlling the access right in a large POSET (partially ordered set) hierarchy to reduce the required computation for key generation and derivation with the storage amount of data decreased.
