    MOSAIC: Masked Outsourcing of Secure AI Computations

    James Hsin-yu Chiang, Sheila Zingg, Kari Kostiainen, Srdjan Capkun

    cs.CR · cs.AI

    We address the challenge of securely and efficiently outsourcing AI computations from a trusted but computationally weak client to an untrusted but powerful server, in the setting where the client holds both the input and the model, and the server must learn neither. We present MOSAIC, whose core is a novel matrix-multiplication masking protocol that scales to far larger matrices than prior work, enabling the safe outsourcing of modern...

    Memory Provenance Laundering in LLM Agents: A Non-Amplification Firewall for Persistent Memory

    Jinghan Xu, Yiyong Xiao, Wanru Shao, Hankai Liu, Xinjin Li

    cs.CR · cs.AI

    Long-term memory lets large language model(LLM) agents reuse prior preferences and work flows, but it also turns untrusted observations into persistent action context. We identify memory provenance laundering: during LLM-based memory consolidation, an external observation may be rewritten as apparent user history or workflow support, preserving an action trigger while erasing the low-trust source that should limit its authority. Existing...
