LCGuard: Latent Communication Guard for Safe KV Sharing in Multi-Agent Systems
Researchers have developed LCGuard, a new framework designed to enhance security in multi-agent large language model (LLM) systems. This system addresses the risks associated with latent communication, specifically through transformer key-value (KV) caches, which can inadvertently leak sensitive information between agents. LCGuard works by transforming KV cache artifacts to reduce the reconstructability of sensitive data while preserving task-relevant information, thereby improving safety without significantly impacting performance.
