With the rapid development of electronic and information technology, Internet of Things (IoT) devices have become extensively utilised in various fields. Increasing attention has been paid to the performance and security analysis of IoT-based services. Dynamic instrumentation is a common process in software analysis for acquiring runtime information. However, due to the limited software and hardware resources in IoT devices, most dynamic instrumentation tools do not support IoT-based services. In this paper, we provide an analysis tool, IoTDIT, to solve the current problem of runtime detection in IoT-based services. IoTDIT employs static analysis and ptrace system calls to obtain dynamic firmware information, which can aid in firmware performance analysis and security detection. We perform experiments to verify the performance and effectiveness of the proposed instrumentation tool.

随着电子和信息技术的飞速发展，物联网（IoT）设备已广泛应用于各个领域。人们越来越重视基于物联网的服务的性能和安全性分析。动态检测是软件分析中用于获取运行时信息的常见过程。但是，由于IoT设备中有限的软件和硬件资源，大多数动态仪表工具不支持基于IoT的服务。在本文中，我们提供了一个分析工具IoTDIT，以解决当前基于IoT的服务中的运行时检测问题。IoTDIT采用静态分析和ptrace系统调用以获取动态固件信息，这有助于进行固件性能分析和安全检测。我们进行实验以验证所提出的检测工具的性能和有效性。
