Services for Intel hardware-based Trusted Execution Environments (TEEs)
Intel provides both registration and provisioning services for selected Intel® Xeon® E processors and Intel® Xeon® Scalable processors (starting from 3rd generation). These services support both Intel® Software Guard Extensions (Intel® SGX) and Intel® Trust Domain Extension (Intel® TDX) services, providing the data and collateral to enable third-party remote attestation using the Elliptic Curve Digital Signature Algorithm (ECDSA).
Intel® SGX and Intel® TDX Registration Service
Intel provides the Registration Services to create a package that will register platform root keys (PRKs) shared between all processors on a platform. Visit the Intel® SGX and Intel® TDX Registration Service page for more information.
Intel® SGX and Intel® TDX Provisioning Certification Service
Intel provides Provisioning Certification Services enabling retrieval of necessary collaterals to attest the Intel® SGX-enabled enclave or an Intel® TDX trusted virtual machine (VM). To learn more and subscribe to the service, visit our Intel® SGX and Intel® TDX Provisioning Certification Service page.
Intel® SGX Attestation Service Utilizing Enhanced Privacy ID (EPID)
The Intel® SGX Attestation Service utilizing EPID is only available on select client systems, select Intel® Xeon® E3 processors, and selected Intel® Xeon® E processors.
Intel SGX Attestation Service enables a relying party to attest an enclave without knowing the specific Intel® processor that the enclave is executing on. To learn more and subscribe to the service, visit our Intel® SGX Attestation Service page.
Attestation Service utilizing EPID is only available on selected client systems, selected Intel® Xeon E3 processors, and selected Intel® Xeon E processors.
