摘要

TrustZone是ARM架构的扩展，它允许在ARM处理器中执行的软件在两个环境中分离:运行通用操作系统(例如，Android或Linux)及其应用程序的正常世界，以及运行安全服务或其他需要与正常世界隔离的安全世界。本工作旨在为从安全世界分析正常世界的安全状况提供支持。为此，我们提出了一个利用TrustZone架构的虚拟机自省(VMI)库。VMI工具和库在安全环境中运行，并检查正常环境。我们在i.MX53开发板上对库进行了实验评估。

Introspection for ARM TrustZone with the ITZ Library

TrustZone is an extension of the ARM architecture that allows software executed in ARM processors to be split in two environments: the normal world that runs a common operating system (e.g., Android or Linux) and its applications, and the secure world that runs security services or others that need to be isolated from the normal world. This work aims to provide support for analyzing the security status of the normal world from the secure world. For this purpose, we present a Virtual Machine Introspection (VMI) library that leverages the TrustZone architecture. VMI tools and the library run in the secure world and inspect the normal world. We present an experimental evaluation of the library in an i.MX53 development board.
