Abstract
A description is given of ASDViews, an implementation of views as the security object in a multilevel secure relational database management system (DBMS) that results in a small trusted computing base (TCB) as required to meet the criteria for evaluation class B2 and above. A general view is the result of a database query. Since most of the code which implements the DBMS is involved in processing the query, most of the DBMS must be trusted. ASDViews is defined using a subset of the relational algebra to restrict the size of the query language available to define a secure view. This approach reduces that part of the TCB required to implement secure views to roughly 1000 lines of code Author(s) Garvey, C. TRW Defense Syst. Group, Redondo Beach, CA, USA Wu, A.Keywords
