Secure transaction processing in firm real-time database systems
Binto George, Jayant R. Haritsa · 1997
Many real-time database applications arise in safety-critical installations and military systems where enforcing security is crucial to the success of the enterprise. A secure real-time database system has to simultaneously satisfy who requirements guarantee data security and minimize the number of missed transaction deadlines. We investigate here the performance implications, in terms of missed deadlines, of guaranteeing security in a real-time database system. In particular, we focus on the concurrency control aspects of this issue.
