Multilevel Secure Database Management Prototypes
The three systems described in this essay each target the most stringent security standards embodied in the A1 requirements as defined by the US Department of Defense " Trusted Computer Systems Evaluation Criteria " [DOD85], which is commonly called the Orange Book. While the initial designs of all these systems — and in some cases the implementations — predate the " Trusted Database Management...
متن کاملMultilevel Secure Database Encryption with Subkeys
In this paper, we propose a multilevel database encryption system with subkeys. This new system is called the record-oriented cryptosystem which encrypts each record with different field-subkeys according to a security class of the data element. Each field is decrypted individually by the field-subkeys of which security class is higher than or equal to that of the encrypted field-subkeys. This ...
متن کاملIntegrity in Multilevel Secure Database Management Systems
Integrity is usually considered to be at odds with security in multilevel databases. Integrity constraints enforce conditions on relations between data, while security constraints enforce separation between data. If an integrity constraint is defined over data at different security levels, a direct conflict results. However, the solution is not to sacrifice the integrity constraint altogether. ...
متن کاملTowards the Design and Implementation of a Multilevel Secure Deductive Database Management System
In this paper we describe a preliminary design and implementation of a multilevel secure deductive database management system (MLSIDEDBMS). In particular, logic as a dara model for multilevel databases, reasoning across security levels, architectural issues for an MLSIDEDBMS, and a prototype implementation are discussed.
متن کاملTowards a Multilevel Secure Database Management System for Real-Time Applications
Database systems for real-time applications must satisfy timing constraints associated with transactions, in addition to maintaining data consistency. In addition to real-time requirements, security is usually required in many applications, because sensitive information must be safeguarded. Multilevel security requirements introduce a new dimension to transaction processing in real-time databas...
