一、内容摘要（Content summary）

本期推文将从思维导图、精读内容、知识补充三个方面介绍精读期刊论文《混源操作系统供应链安全风险评估方法研究》的5.结束语。

This issue of tweets will introduce the 5. Conclusion testing of the journal paper "Research on Supply chain Security Risk assessment Method of Mixed source Operating System" from three aspects: mind mapping, intensive reading content, and knowledge supplement.

二、思维导图（Mind Mapping）

三、精读内容（Detailed Reading Content）

在该小节，作者对论文的内容进行了总结。首先是研究背景，针对具有多样代码来源、大规模和复杂结构的混源操作系统，缺乏适用的供应链风险评估方法。其次是研究内容，本文提出以可溯性、可用性、安全性为核心保障目标，通过分析其供应链特点构建了定制化的风险评估指标体系，并设计量化评估方法，经案例验证具备可行性与有效性。最后是研究意义，该研究还整合了辅助评估的技术工具，为生产者发现产品供应链中的薄弱环节提供有效支持，帮助生产者识别薄弱环节并支持跨系统安全风险横向对比，为混源操作系统的供应链安全管理提供了理论与实践依据。

In this section, the author summarizes the content of the paper. Firstly, regarding the research background, for mixed-source operating systems with diverse code sources, large scale and complex structures, there is a lack of applicable supply chain risk assessment methods. Secondly, regarding the research content, this paper proposes to take traceability, availability and security as the core guarantee goals. By analyzing the characteristics of its supply chain, a customized risk assessment index system is constructed, and a quantitative assessment method is designed. It has been verified through cases to be feasible and effective. Finally, regarding the research significance, this study also integrates technical tools for auxiliary assessment, providing effective support for producers to identify weak links in the product supply chain. It helps producers recognize weak links and supports horizontal comparisons of security risks across systems, offering theoretical and practical basis for the supply chain security management of mixed-source operating systems.

四、知识补充（Knowledge Supplementation）

（一）符号执行（Symbolic execution)

符号执行是一种程序分析技术，通过将程序输入抽象为符号而非具体值，动态探索程序路径并推导路径约束条件，广泛应用于软件测试、漏洞挖掘和程序验证等领域。

Symbolic execution is a program analysis technique that abstracts program inputs into symbols rather than concrete values, dynamically explores program paths, and deduces path constraints. It is widely used in fields such as software testing, vulnerability mining, and program verification.

模糊测试是一种自动化软件测试技术，通过向目标系统提供非预期的、随机的或畸形的输入数据，并监控系统异常（如崩溃、内存泄漏或断言失败）来发现软件缺陷。

Fuzz testing is an automated software testing technique that discovers software defects by providing unexpected, random or abnormal input data to the target system and monitoring system anomalies such as crashes, memory leaks or assertion failures.
