Abstract
Mobile distributed real-time databases are needed in security-critical applications, e.g., e-commerce, stock trading system, and military applications. In these applications, mobile distributed real-time database systems have to simultaneously satisfy two requirements in guaranteeing data security and minimizing the deadline miss ratio for admitted transactions. Multilevel secure database system based on mandatory access control can prevent direct unlawful information flows between transactions belonging to different clearance levels. However, it cannot prevent the covert communications between transactions belonging to different clearance levels. This paper presents a secure hybrid optimistic real-time concurrency control protocol (SHORTCC). The protocol not only considers carefully the inherent characteristics of mobile environment and the timing constraints of time-critical applications, but also achieves data security without sacrificing real-time performance significantly.
