چکیده

Security has become an important characteristic for many real-time systems. Due to the lack of enough and stable energy supply in battery-powered embedded systems, one of the foremost challenges is the mismatch between energy and performance requirements of security processing. In this paper, we propose a security-aware and energy-efficient scheduling algorithm that aims at reducing energy consumption while ensuring the real-time and security requirements. Based on the feedback control theory, we employ a feedback unit to keep track of the CPU utilization and manage the security level dynamically. Simulation results show the effectiveness and efficiency of the proposed algorithm.

Open Issues and Challenges in Security-aware Real-Time Scheduling for Distributed Systems

Task Scheduling for real-time distributed systems has been investigated extensively in the literature. However, conventional wisdom in dynamic scheduling ignores security requirements in realtime applications. As such, in addition to factoring quality of security in real-time applications running in the system, real-time scheduling algorithms need to be security-aware in nature. In this paper w...

Security-Aware Periodic-Write Scheduling for Mission-Critical Embedded Storage System

⎯High quality of security and guaranteed real-time requirements are two key goals of missioncritical embedded storage systems. But most existing real-time disk scheduling algorithms do not consider improving security performance of disk requests. A security-aware periodic-write (SAPW) scheduling algorithm is proposed to judiciously select appropriate security level for each disk request to maxi...

Enhanced Energy-Aware Feedback Scheduling of Embedded Control Systems

Dynamic voltage scaling (DVS) is one of the most effective techniques for reducing energy consumption in embedded and real-time systems. However, traditional DVS algorithms have inherent limitations on their capability in energy saving since they rarely take into account the actual application requirements and often exploit fixed timing constraints of real-time tasks. Taking advantage of applic...
