On April 2, 2025, Intel discontinued the Intel® SGX Attestation Service Utilizing Intel® EPID. This included all active API versions.
Intel recommended users of Intel SGX Attestation Service Utilizing Intel EPID migrate to one of several attestation alternatives offered by Intel ahead of the end-of-life date:
- Intel® Tiber™ Trust Authority – a Zero Trust attestation software as a service (SaaS)
- Intel® Software Guard Extensions Data Center Attestation Primitives (Intel® SGX DCAP) with ECDSA-based Attestation
Background
Many Intel products that originally supported Intel SGX and enabled the use of Intel SGX Attestation Service Utilizing Intel EPID have exceeded their end of servicing lifetime dates. More recent products exclusively support Intel SGX DCAP with ECDSA-based attestation. Intel elected to focus future enabling support on more recent products.
