Abstract
In many real-time applications, security is another important requirement, since the secure real time database system maintains sensitive information to be shared by multiple users with different levels of security clearance or to be attacked by hackers with ill will. Encryption policies are necessary for the security of secure real-time database systems in addition to the existing security methods, too. However, there has not been much work for the encryption policies in secure real-time database systems, although sensitive information must be safeguarded in real-time systems as well. In this paper, we propose a encryption manager for the purpose of solving the encryption policies of the secure real-time database systems. What is important in the encryption policies of secure real-time database systems is security and timeliness. A significant feature of the proposed encryption manager is the ability to dynamically adapt a encryption algorithm that consider transaction deadline and security level.
