CT-M: Hardware Containers for Software Components - Detection and Recovery at the Hardware/Software Interface

本项目侧重于硬件特性，以提高软件系统的安全性。通过细化当前体系结构中可用的粗粒度保护，该项目将致力于保护单个软件对象或组件的完整性。硬件机制强制严格控制软件组件的执行，程序员可以将其定义为大到整个应用程序或小到单个对象。目标是快速检测并从正确访问内存或接管CPU的攻击中恢复。该方法还包括硬件监督恢复，使系统能够在攻击后恢复正常运行，并保护恢复过程本身免受攻击。这个项目的好处包括能够阻止大规模的攻击，以及在未来开发更健壮的软件系统的潜力。与攻击预防或检测相比，恢复受到的关注较少，但对于没有人工操作员干预的嵌入式系统来说，恢复尤为重要。该项目将用于培训研究生，并为三所参与大学的研究生课程提供材料。还将开发用于K-12教育的模块，目的是吸引学生考虑从事计算机科学和工程方面的职业。

This project focuses on hardware features to improve the security of software systems.By refining the coarse-grained protections available intoday's architectures, the project will aim to protectthe integrity of individual software objects or components.The hardware mechanisms force tight controls on the execution of software components, whichprogrammers can define to be as large as entireapplications or as small as individual objects. The goal is to rapidly detect and also recover from attacks thatimproperly access memory or take over the CPU.The approach also includes hardware-supervisedrecovery, to enable systems to return to normal operation after an attack and to protect the recovery process itself from attacks.The benefits of this project include the ability to thwart a large class of attacks and the potential ofdeveloping more robust software systems in the future.Recovery, which has received somewhat less attention thanattack prevention or detection, is especially important for embedded systems that do not have the luxury of intervention by human operators.The project will be used to train graduate students and to feed material into graduate courses taught at the three participating universities. Modules will also be developed for use in K-12 education with the aim of drawing students into considering careers in computer science and engineering.
