EMBEDDED SECURE DATA BASE MANAGEMENT SYSTEM (ESDBMS)

THE USE OF COMMERCIAL DATA BASE MANAGEMENT SYSTEM (DBMS) FOR REAL-TIME COMMAND, CONTROL, AND COMMUNICATIONS (C3) SYSTEMS IS OFTEN TECHNICALLY FEASIBILITY. COMMERCIAL DBMSS ARE OFTEN CLOSELY TIED TO GENERAL-PURPOSE OPERATING SYSTEMS NOT SUITED FOR REAL-TIME APPLICATIONS. COMMERCIAL DBMSS ALSO DO NOT SUPPORT MULTILEVEL APPLICATIONS (I.E., ACCESS TO OPERATIONAL DATA OF VARIOUS SENSITIVITIES BY OPERATORS WITH DIFFERENT CLEARANCES). THE TECHNICAL STATE-OF-THEART NOW ALLOWS BOTH OF THESE DEFICIENCIES TO BE ADDRESSED. THE THEORETICAL CONCEPTS NEEDED HAVE BEEN DEMONSTRATED AS PART OF THE SEAVIEW PROJECT, SHOWING THAT A HIGHLY-ASSURED SYSTEM WITH DBMS FUNCTIONALITY CAN BE IMPLEMENTED AS AN UNTRUSTED DBMS EXECUTING ON A HIGHLY-TRUSTED SECURITY KERNEL, WITH ADEQUATE PERFORMANCE. FOR THE PROPOSED PROJECT, CALLED THE EMBEDDED SECURE DBMS, WE PROPOSE TO PORT A HIGH-PERFORMANCE DBMS (VIZ., ORACLE OR EQUIVALENT) TO GEMSOS IN SUCH A WAY AS TO ADEQUATELY SUPPORT REAL-TIME, EMBEDDED MULTILEVEL APPLICATIONS. THIS PROPOSAL IS SYNERGISTIC WITH AN ONGOING PRODUCT DEVELOPMENT EFFORT TO PROVIDE A MULTILEVEL SECURE VERSION OF ORACLE IN THE CONTEXT OF A GENERAL-PURPOSE OPERATING SYSTEM. THE ESDBMS WILL BE FOCUSED PRIMARILY UPON THE ISSUE OF DESIGNING AND DEVELOPING A RUN-TIME EXECUTIVE WHICH SUPPORTS THE MULTILEVEL VERSION OF ORACLE AND ALLOWS HIGH-PRIORITY TRANSACTIONS TO BE PROCESSED IN REAL-TIME REGARDLESS OF SYSTEM LOAD.
