Secure Multi-Tenant Architecture Prevents LLM Data Leakage
7.7
In a Jan. 10, 2026 arXiv preprint, Qiang Zhang presents a Secure Multi-Tenant Architecture (SMTA) and Burn-After-Use (BAU) mechanism to prevent data leakage in enterprise LLM deployments. The authors evaluate SMTA across 127 test iterations including 55 infrastructure-level attack tests (92% defense rate) and BAU across 72 iterations (76.75% success) on four leakage metrics, noting residual risks from misconfigured credentials and logging.
Key Points
- 1Demonstrates SMTA isolates tenants, achieving 92% defense success across 55 infrastructure attack tests
- 2Introduces BAU ephemeral contexts, reducing post-session leakage with 76.75% success over 72 iterations
- 3Highlights residual risks from credential misconfiguration and observability, requiring hardened secrets and logging controls
Scoring Rationale
Strong experimental evaluation and clear mitigation approach; limited by single-source arXiv preprint and residual infrastructure risks.
