Introduction

NVIDIA Attestation APIs return verification results as Detached Entity Attestation Token (EAT) Bundles, following the RFC 9711 standard. This format provides a structured way to report attestation status for systems that may contain multiple hardware entities.

Understanding the Token Structure

The attestation response consists of a set of JSON Web Tokens (JWTs) organized as follows:

• Overall Token: The primary JWT that provides the high-level attestation result for the entire request.

• Detached Claims: Individual JWTs that contain detailed verification data for each specific device (e.g., a specific GPU or Switch) identified in the request.

By using detached claims, the verifier can provide granular evidence for each hardware component while maintaining a unified summary in the overall token.

Claims Reference Guide

The specific claims available within these tokens depend on the hardware type and the version of the attestation service. Use the links below to view the detailed claim definitions:
