Intel audits configuration on system launch and verifies it runs something they know safe. That involves CPU, CPU microcode, BIOS version and a few other things (SGX may not work if you don't have the right RAM for example).
The final signature comes in the form of a x509 cerificate signed with ECDSA.
What's more important to me is that SGX still has a lot of security researchers attempting (and currently failing) to break it further.
