基于软件故障注入的嵌入式系统鲁棒性测试

Robustness testing of embedded software based on fault injection

以研究对嵌入式系统鲁棒性进行评价和基于软件故障注入技术的嵌入式系统鲁棒性测试为目的。对嵌入式系统鲁棒性测试的相关概念以及软件故障注入技术原理进行了介绍,以Linux操作系统内核函数测试为例,通过对系统API参数的故障注入接口进行分析,提出基于GDB工具的软件故障注入方法来实现系统鲁棒性故障注入测试。完成了相应的Linux操作系统API接口故障注入测试实例并给出了测试结果。为嵌入式系统鲁棒性测试提供了更为直观、有效的方法。

To study the robustness of the evaluation of embedded systems and software-based fault injection testing of embedded systems for the purpose of robustness. Test the robustness of the embedded system and software faults related concepts were introduced into the technical principles, The Linux operating system kernel function tests, for example, parameters of the system through the API interface fault injection analysis, based on GDB tools to implement software fault injection method robustness fault injection testing. Completed a corresponding API interface, Linux operating system fault injection test cases and test results are given. To test the robustness of embedded systems to provide a more intuitive and effective way.
