AI总结:

本文提出了一种基于软件的低级内存保护系统,以防御物理攻击向量引起的内存安全问题。

摘要:

编程错误、缺陷硬件组件(如硬盘主轴缺陷)以及环境危险可能导致无效的内存操作。此外,不可预测的环境应力形式,如辐射、热影响和能量波动,可以引发硬件故障。有时,软错误而不是完全失败会发生,例如位翻转。导致位翻转的'自然'因素可以通过有针对性的攻击复制,从而导致重大损害,包括完整的特权系统访问。现有的物理防御解决方案在部署后不久就被绕过了。我们将探讨一种新的软件基于的低级层,可以保护受物理攻击向量影响的易受攻击的内存,特别是与位翻转漏洞相关的攻击。

英文摘要:

Programming errors, defective hardware components (such as hard disk spindle defects), and environmental hazards can lead to invalid memory operations. In addition, less predictable forms of environmental stress, such as radiation, thermal influence, and energy fluctuations, can induce hardware faults. Sometimes, a soft error can occur instead of a complete failure, such as a bit-flip. The 'natural' factors that can cause bit-flips are replicable through targeted attacks that result in significant compromises, including full privileged system access. Existing physical defense solutions have consistently been circumvented shortly after deployment. We will explore the concept of a novel software-based low-level layer that can protect vulnerable memory targeted by physical attack vectors related to bit-flip vulnerabilities.
