KV-Cache Side Channel Reliability Collapses Under LLM Serving Load

Researchers have investigated the reliability of KV-cache timing side channels in multi-tenant LLM serving environments. Their experiments revealed that contention from multiple users significantly degrades the reliability of these side channels, potentially overestimating their operational attack viability on quiet systems. The study found that concurrency depth and the serving stack heavily influence the effectiveness of such attacks. AI

IMPACT Understanding KV-cache side-channel vulnerabilities is crucial for securing multi-tenant LLM deployments and ensuring data privacy.

    Characterizing Contention-Induced Reliability Collapse in KV-Cache Timing Side Channels for Multi-Tenant LLM Serving

    arXiv:2609.06853v1 Announce Type: cross Abstract: Shared key--value (KV) cache reuse improves large language model (LLM) serving, but it can also create a timing side channel that reveals whether a prefix is already cached. Previous work shows that such attacks are possible, but …
