Silicon Trust Domain Architecture

Intel® TDX (Trust Domain Extensions)

Intel TDX introduces hardware-managed virtual machine (VM) isolation, creating cryptographically secure Trust Domains (TDs).

• Memory Encryption: Hardware-managed AES-128/256 engine encrypts the guest TD memory page-by-page.
• Hypervisor Isolation: The host VMM (Virtual Machine Monitor) or root administrator is blocked from inspecting or modifying the memory state of the guest enclave.
• Hardware Attestation: Trust Domains generate hardware-signed reports to prove they are running authentic, un-tampered code on true TDX silicon.

Zero-Trust Mesh (Kuma)

Multi-zone communication is federated and secured dynamically through Kuma Service Mesh.

All data plane proxies communicate over strict mutual TLS (mTLS) with custom traffic permission boundaries, ensuring that confidential data in transit cannot be snooped or manipulated.

Lightweight Container Orchestration (K3s)

We use K3s as a lightweight, secure container orchestrator. It allows deploying and running the entire sovereign application stack inside minimal resource profiles directly at regional "Confidential Cape" buildings.
