FAQs in Build and Run

Why did I see SGX launch check failed: Env var for IAS SPID or IAS KEY does NOT exist.

Because the Intel Attestation Service (IAS) requires mutual authentication in TLS communications. So if you have followed build prerequisite document for Intel Attestation Service (IAS) registration, you should be able to obtain the SPID, Primary Key, and Secondary Key . Please set them as environment variables, e.g. export IAS_KEY=..., and then configure them in the ias_client_config section of config.toml accordingly.

MesaTEE uses the most recent Intel IAS API version 5. It no longer requires certificate from IAS client. Instead, it requires a Subscription Key for access. Please read the manual and build prerequisite for details.
