Intel Trust Authority (formerly Amber)

Intel Trust Authority, initially introduced as Project Amber, is a suite of trust and security services that provides remote attestation for the verification of Trusted Execution Environments (TEEs). As of 2026, it serves as the backbone for Confidential AI, enabling enterprises to verify that their sensitive workloads are running on genuine, up-to-date hardware, such as Intel Xeon processors with SGX or TDX, and Intel Gaudi AI accelerators. Unlike traditional security models that rely on the cloud provider's integrity, Intel Trust Authority acts as a decoupled, third-party authority, providing a hardware-rooted 'seal of approval.' This architecture is critical for multi-party computation and federated learning, where data sovereignty and model IP protection are paramount. The service works across hybrid, edge, and multi-cloud environments, ensuring that security policies are enforced consistently regardless of the underlying infrastructure. By providing cryptographically signed evidence (tokens) that a TEE is correctly configured and uncompromised, it enables a 'verify before you trust' paradigm essential for highly regulated sectors like finance, healthcare, and government defense.
