Implementation Issues in Multilevel Security for Object-Oriented Databases

Abstract : This report concentrates on implementation issues associated with the security model for object-oriented databases. The discussion of model is conducted from the implementation point of view. Certain characteristics the model possesses, make its implementation a conceptually simple matter. Two alternative approaches to the subject of implementation are analyzed. Finally, the requirements the model places on the implementation of the object layer are explained in detail. Keywords: TDI(Trusted Database Implementation), Message filtering algorithms, Information flows.
