STAR: secure real-time transaction processing with timeliness guarantees
23rd IEEE Real-Time Systems Symposium, 2002. RTSS 2002.
Preserved Fulltext
Real-time databases are needed in security-critical applications, e.g., e-commerce, agile manufacturing, and military applications. ...
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 ...
Conclusions and Future Work In this paper, we presented a novel real-time database architecture for secure transaction processing with certain miss ratio guarantees. ...
