Unlearning at Scale: Implementing the Right to Be Forgotten in Large Language Models

We study the right to be forgotten GDPR Art. 17 for large language models and frame unlearning as a reproducible systems problem. Our approach treats training as a deterministic program and logs a minimal per-microbatch record ordered ID hash, RNG seed, learning-rate value, optimizer-step counter...

Yet Another Mirage of Breaking MIRAGE: Debunking Occupancy-Based Side-Channel Attacks on Fully Associative Randomized Caches

Recent work presented at USENIX Security 2025 claims that occupancy-based attacks can recover AES keys from the MIRAGE randomized cache. In this paper, we examine these claims and find that they arise from fundamental modeling flaws. Most critically, the authors' simulation of MIRAGE uses a...

Can AI Keep a Secret? Contextual Integrity Verification: a Provable Security Architecture for LLMs

Large language models LLMs remain acutely vulnerable to prompt injection and related jailbreak attacks; heuristic guardrails rules, filters, LLM judges are routinely bypassed. We present Contextual Integrity Verification CIV, an inference-time security architecture that attaches cryptographically...
