The Graham-Denning Model
In 1972, G.S. Graham and P.J. Denning, developed the Graham-Denning Model that shows how subjects and objects should be securely managed to include creation and deletion. It also addresses how to assign specific access rights. The model is set up based on subject, object, and rules that tie in both. The Graham-Denning model resolves the security questions related to defining a set of specific rights on “how particular subjects can execute security functions on an object.” (Pfleeger & Pfleeger, 2003) The eight access rights include the creation and deletion of object, subject and access rights for read, grant, delete, and transfer.

A threshold gate is described by its children $n_x$ and a threshold value $t_x$, where $0iteup{di2007over} is a technique that makes use of a two-layer encryption to enforce selective encryption without requesting the data owner to re-encrypt the data every time there is a change in the AC policy. In the over-encryption technique, two layers of encryption are imposed on data: the inner layer is applied by the data owner to provide initial protection, and the outer layer is done by the server to reflect access control policy changes. Intuitively, this technique allows data owners outsource, besides their data, authorization and revocation tasks on their data to a semi-trusted server without revealing the underlying data to the
