An Investigation of Secure Distributed DBMS Architectures

The objective of this paper is to describe an architecture for a multilevel secure distributed database management system (SD-DBMS). This work was part of a project, funded by Rome Air Development Center (RADC), to design a multilevel secure (MLS) database management system (DBMS) capable of processing information at a minimum of three classification levels and/or categories. The SD-DBMS was designed in accordance with the Trusted Computer System Evaluation Criteria (TCSEC) requirements for a Class B3 trusted computer system [Cen85b].
