Abstract
A multilevel relational database represents information in a multileve l state of the world, which is the knowledge of the truth value of a s tatement with respect to a level in a security lattice. We develop a s emantic framework of the multilevel secure relational model with tuple -level labeling, which formalizes the notion of validity in multilevel relational databases. We also identify the multilevel security proper ties that precisely characterize the validity of multilevel relational databases, which can be maintained efficiently. Finally, we give an u pdate semantics of the multilevel secure relational model that preserv es both integrity and secrecy.
