Authentication Error When Using Different Service Provider ID (SPID) with Intel® Software Guard Extensions Attestation Service (Intel® SGX Attestation Service)

Content Type: Troubleshooting | Article ID: 000089323 | Last Reviewed: 04/26/2022

Description Resolution Additional information

Description

Communication with a service provider is possible if two clients communicate using the same SPID, but authentication errors occur if each client uses a different SPID.

Resolution

In remote attestation, the service provider application gets one SPID. Each enclave that wants to attest and communicate with that service provider must use that service provider's SPID. An enclave cannot attest to a service provider with a different SPID.
