安全性是实时系统(RTS)日益关注的问题。在过去十年左右的时间里，研究人员展示了针对这类系统的攻击和防御。在本文中，我们对该领域的安全研究的有效性进行了识别、分类和衡量。我们提供了这一现有工作的高级别摘要[标识]和分类[分类]。此外，我们对基于调度器的安全技术进行了深入的分析[测量]--这是最常见的一类实时安全机制。为此，我们开发了一个通用的度量“攻击者的负担”，用于衡量(现有的和未来的)基于调度器的实时安全措施的有效性。该指标建立在“工作因数”概念的基础上[1]，适用于各种基于调度器的实时安全技术，并在这些技术之间进行了标准化。
Security is an increasing concern for real-time systems (RTS). Over the last decade or so, researchers have demonstrated attacks and defenses aimed at such systems. In this article, we identify, classify and measure the effectiveness of the security research in this domain. We provide a high-level summary [identification] and a taxonomy [classification] of this existing body of work. Furthermore, we carry out an in-depth analysis [measurement] of scheduler-based security techniques — the most common class of real-time security mechanisms. For this purpose, we developed a common metric, “attacker’s burden” , used to measure the effectiveness of (existing as well as future) scheduler-based real-time security measures. This metric, built on the concept of “work factor” [1], is adapted for, and normalized across, various scheduler-based real-time security techniques.
