Node Attestation: (Hardware Integrity)
Fortanix's Node Agent, which sits on each enrolled compute node, starts the node attestation process.
The node agent sends evidence of attestation to Fortanix CCM. Fortanix CCM, in turn, sends evidence of attestation to IAS (Intel Attestation Service). IAS checks the evidence and sends it back to Fortanix CCM.
Once attestation passes, then Fortanix CCM issues a node agent certificate.
