Abstract
The authors describe the design of a secure database system,LDV (Lock Data Views), that builds upon the classical security policies for operating systems. LDV is hosted on the LOgical Coprocessing Kernel (LOCK) Trusted Computing Base (TCB). LDVs security policy builds on the security policy of LOCK. Its design is based on three assured pipelines for the query, update, and metadata management operations. The authors describe the security policy of LDV, its system architecture, the designs of the query processor, the update processor, the metadata manager, and the operating system issues. LDVs solutions to the inference and aggregation problems are also described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
