LLMs struggle with symbolic security protocol analysis, study finds

A new study published on arXiv evaluates the capabilities of Large Language Models (LLMs) like GPT and DeepSeek in performing symbolic security protocol analysis. The research found that while LLMs can achieve high recall for certain security goals, their precision is generally low, and their verdicts can be unstable across different runs. Reasoning modes of LLMs showed better precision but detected fewer attacks compared to chat modes, with authentication goals proving particularly challenging. Although LLMs do not yet match the performance of dedicated formal verification tools like ProVerif and OFMC, they may serve as preliminary screening filters for security protocols. AI

IMPACT LLMs show potential as preliminary filters for security protocol analysis but do not yet match formal verification tools.

    Evaluating Large Language Models for Symbolic Security Protocol Analysis

    arXiv:2607.20712v1 Announce Type: cross Abstract: Security protocol verification relies on formal tools such as ProVerif and OFMC. This study evaluates whether Large Language Models (LLMs) can perform comparable analysis. We test GPT and DeepSeek in chat and reasoning modes over …
