LLM-Generated Passphrases That Are Secure and Easy to Remember

NAACL 2025findings

Automatically generated passwords and passphrases are a cornerstone of IT security. Yet, these passphrases are often hard to remember and see only limited adoption. In this work, we use large language models to generate passphrases with rigorous security guarantees via the computation of the entropy…

Cold Diffusion: Inverting Arbitrary Image Transforms Without Noise

NeurIPS 2023poster

Standard diffusion models involve an image transform -- adding Gaussian noise -- and an image restoration operator that inverts this degradation. We observe that the generative behavior of diffusion models is not strongly dependent on the choice of image degradation, and in fact, an entire family…
