The Security Vulnerability of Standard GPU Memory Busses
In standard GPU clusters, data traveling across PCIe buses and system memory is vulnerable to physical probing, bus snooping, or malicious hypervisor inspection. For highly regulated enterprises (defense, banking, healthcare), ensuring absolute data confidentiality during distributed inference is mandatory.
Coordinating NVIDIA Confidential Computing Across Cluster Nodes
InferCluster orchestrates hardware-level encryption across multi-node GPU clusters. Utilizing NVIDIA Confidential Computing (H100 CC) and AMD SEV-SNP CPU enclaves, InferCluster encrypts all data in transit across NVLink and InfiniBand interconnects, ensuring memory contents remain cryptographically sealed against physical inspection.
Remote Attestation and Cluster Node Verification
Before integrating a newly provisioned worker node into an active confidential cluster group, InferCluster's control plane executes remote attestation protocols, verifying cryptographic hardware certificates issued by the GPU manufacturer's root of trust.
Zero-Trust Multi-Tenant Enclave Isolation
Within shared enterprise clusters, InferCluster ensures that tenant workloads execute inside isolated TEE enclaves. Decryption keys are held in secure hardware security modules (HSMs) and released only after successful zero-trust identity verification.
