| Abstract: |
| Rust is an emerging type-safe, memory-safe, and concurrency-safe programming language for system programming to address security issues in the system programming domain. The design of Rust emphasizes both security and high performance, thus has been increasingly used in the construction of software infrastructures such as operating system kernels, Web browsers, network protocol stacks, databases, and blockchains. However, existing research efforts have demonstrated that despite its design goal of ensuring security, Rust still suffers from many safety issues. As a system programming language, the security of Rust directly affects the security of software systems developed with Rust. Furthermore, with the widespread adoption of Rust, the study of Rust language security is becoming a hot research topic with significant research progress. In this survey, we systematically analyze and summarize the latest research progress in this field, based on a systematic analysis of 46 published research papers: first, we analyze the main security-related features of Rust, including functional programming paradigm, strong polymorphic type system, automatic ownership-based memory management model, and explicit isolation of unsafe code; second, we propose a taxonomy to classify current research efforts into four categories: empirical security study, vulnerability detection, safety enhancement, and formal verification, by reviewing and analyzing, and summarizing the relevant research not only in each of these four directions, but also in their interactions; finally, we point out open problems in this research area, and highlight the remaining challenges of Rust language security research, and propose four potential research directions. This survey serves as both a valuable reference and a starting point for future research in this field. |
