<p>In an era where software systems underpin critical infrastructure, ensuring their security and reliability is paramount. However, the evolving complexity of modern software poses significant challenges for traditional security measures.
Our project is dedicated to fortifying software security and reliability through a multifaceted approach that integrates cutting-edge techniques and methodologies. We focus on leveraging advanced technologies such as Large Language Models (LLMs) and Static Program Analysis to safeguard individual program and software supply chains against a wide range of security threats. Ultimately, our goal is to empower organizations to proactively identify, mitigate, and prevent security threats, thereby safeguarding critical infrastructure, sensitive data, and user privacy.

<img class="img-resonsive pull-left" src="images/ssc.png" width="260">
<p>Software supply chains play a critical role in delivering reliable and secure software products to end-users. However, recent high-profile security breaches and supply chain attacks have highlighted the vulnerabilities inherent in these systems. This project focuses on enhancing software supply chain security through innovative techniques such as fine-grained program dependency construction, clone detection, vulnerability recognization, vulnerability propagation analysis, security pre-warning, and more. The ultimate goal of this project aligns closely with the principles of AppSecOps, aiming to integrate security practices into the application development and operations processes to enhance the security of software applications throughout their lifecycle. We aims to help organizations build and deploy more secure, resilient, and reliable software applications in today's rapidly evolving threat landscape.</p>

<div class="panel-body">
<img class="img-resonsive pull-left" src="images/llm.png" width="200">
<p>In response to security and reliability issue in individual programs and software supply chain, this project harnesses the power of Large Language Models (LLMs) to revolutionize software security practices. This project aims to develop an advanced software security solution that leverages LLMs to automate and enhance test case generation, vulnerability detection, localization, and repair processes. By harnessing the immense language understanding capabilities of LLMs, we seek to significantly improve the efficiency, accuracy, and scalability of software security practices.</p>

<div class="panel-heading"><h4>Static program analysis based on CPG <a href="https://github.com/orgs/QVoG-BUAA/repositories">[Link]</a></h4></div>
<div class="panel-body">
<img class="img-resonsive pull-left" src="images/cpg.png" width="220">
<p>In addition to leveraging LLMs, we are advancing vulnerability detection through static program analysis. Our project focuses on developing a novel Simplified Code Property Graph (S-CPG), which optimizes away unnecessary nodes and edges compared to the original (Joern) while preserving essential semantic information. Currently, we have implemented S-CPG for C, Java, Python, and ArkTS. We also provide a user-friendly Domain Specific Language (DSL) that enables users to define query patterns on S-CPG intuitively and efficiently, without requiring in-depth knowledge of the underlying graph structure. To date, we have identified over 30 issues in open-source projects, with more than 20 confirmed by project developers. Belows are some CVE-ids discovered by our S-CPG:
CVE-2024-48210, CVE-2025-25623, CVE-2025-29498, CVE-2025-29499, CVE-2025-29502, CVE-2025-4001, CVE-2025-4002, CVE-2025-4003
