STAR: Secure Real-Time Transaction Processing with Timeliness Guarantees
Real-time databases are needed in security-critical applications, e.g., e-commerce, agile manufacturing, and military applications. In these applications, transactions and data items can be classified into several security levels according to their clearance and sensitivity levels. It is essential for real-time databases to prevent illegal direct/indirect transfer of sensitive data, e.g., secret trade, manufacturing, or operational data, between transactions belonging to different security levels. Further, transactions should be committed within their deadlines, i.e., before the market, manufacturing, or battle field status changes. In this paper, we present a novel real-time database architecture, in which illegal direct/indirect inter-level information flows are prevented while controlling the deadline miss ratio for admitted transactions to remain below a certain threshold. In our approach, mandatory access control mechanisms are applied for security purposes. QoS management, ad...
