Trusted Execution Environment for GPU Secure Multi-Tenant Data

The patent segments the virtualized computing environment by creating isolated execution contexts for each tenant using encrypted virtual machines. Each tenant's workloads are confined to their own encrypted VM instance, which is isolated from other tenants even though they share the same physical PPU resources. This segmentation allows multiple tenants to securely share infrastructure while maintaining individual security boundaries.

The patent introduces an intermediary layer of encryption and secure execution environments between the tenants and the shared physical resources. The hypervisor, combined with TEE technology and cryptographic primitives, acts as a mediator that manages resource allocation while preventing unauthorized access. This intermediary layer enables secure multi-tenant sharing by mediating all access requests through security checks and encryption.

The patent implements self-service security mechanisms where the system automatically performs cryptographic key generation, negotiation, and management without requiring manual intervention. The secure microcontroller automatically establishes encrypted communication channels, generates session keys, and manages authentication credentials. This automation reduces operational complexity while maintaining high security standards through consistent, error-free cryptographic operations.

The patent adds a new dimension of security by implementing TEE-based encrypted execution environments alongside the traditional virtualization layer. This creates a multi-layered architecture where security operations occur in a separate cryptographic dimension, using hardware-enforced isolation and cryptographic primitives that operate independently from the software virtualization stack. This dimensional addition provides security without significantly increasing operational complexity.
