提出基于 GPT 的 PagPassGPT,通过引入密码模式结构信息提升命中率,并以分治式 D&C-GEN 减少重复生成,较现有最优模型多猜中12%密码、重复降低25%。

摘要:

在基于深度学习的密码猜测模型激增的背景下,生成高质量密码并减少重复密码的挑战依然存在。为应对这些挑战,我们提出了 PagPassGPT,这是一种构建于 Generative Pretrained Transformer(GPT,生成式预训练 Transformer)之上的密码猜测模型。该模型通过将模式结构信息作为背景知识纳入其中,能够执行模式引导猜测,从而显著提高命中率。此外,我们提出 D&C-GEN 以降低生成密码的重复率,该方法采用分治思想。猜测密码的主要任务被递归划分为互不重叠的子任务。每个子任务继承父任务的知识并预测后续 token。与最先进模型相比,我们提出的方案能够多正确猜测 12% 的密码,同时产生的重复密码减少 25%。

英文摘要:

Amidst the surge in deep learning-based password guessing models, challenges of generating high-quality passwords and reducing duplicate passwords persist. To address these challenges, we present PagPassGPT, a password guessing model constructed on Generative Pretrained Transformer (GPT). It can perform pattern guided guessing by incorporating pattern structure information as background knowledge, resulting in a significant increase in the hit rate. Furthermore, we propose D&C-GEN to reduce the repeat rate of generated passwords, which adopts the concept of a divide-and-conquer approach. The primary task of guessing passwords is recursively divided into non-overlapping subtasks. Each subtask inherits the knowledge from the parent task and predicts succeeding tokens. In comparison to the state-of-the-art model, our proposed scheme exhibits the capability to correctly guess 12% more passwords while producing 25% fewer duplicates.
