Enabling SGX in BIOS and installation of SGX PSW(Platform software) to run applications in secure SGX enclaves.
DCAP infrastructure to support Intel SGX attestation using DCAP PCCS service. PCCS should be running on AWS.
K8s intel SGX plugin/operator support
Automated installation of SGX components
End to end example included to demonstrate the SGX based pod deployment and execution flows.
Application should be based on Graphene/Gramine
OpenVino based application to demonstrate SGX features
SGX device plugin should be utilized to monitor EPC(Enclave Page Cache) usage to schedule pods.
How It Works
Customer enters the Secure and trusted environment and prepares for Smart Edge DEK provisioning. Customer downloads the DEK code from SE github repository
Customer creates a provisionable ISO/Bootable USB
Customer sets up the ESP server
Start the DEK provision process
ESP profile bootstrap process
(This steps involves operations on the local edge cluster and cloud instance which contains the attestation control plane components)
ESP and ESP profile pull the OS image, OS package to create the installable OS.
Customer sets up the AWS Instance with K8s provisioned.
Customer subscribes to PCS and gets API key
Customer deploys controller component for SGX feature (PCCS service on this instance)
End of ESP Phase 1 - enable Intel SGX on the node’s BIOS using Red Fish APIs. Reboot node
ESP continues deploying the DEK components using the Ansible.
SGX device is provisioned with PCCS using PCKIDRetrievalTool.
DEK Cluster is up along with K8s Intel device plugin installed.
Graphenized app is deployed on the kubenetes node using intel device plugin which exposes SGX memory to pods/jobs running on it.

Enable Intel SGX in BIOS
Verify memory settings in System Setup of the BIOS. Keys to look out for –
Memory Operating Mode : Optimizer Mode
Node Interleaving : Disabled
Check if Memory Encryption is enabled/disabled in System Security. Save and Reboot after selection.
Memory Encryption : Single Key
Note here that if you do not see the Disabled button selected when landing on this section, you first need to disable Memory Encryption and then save changes and reboot. Only then, go ahead and choose Single Key here.
Enable SGX and Factory reset together. On selection, Save and Reboot.
Intel(R) SGX : On
SGX Factory Reset : On
Check SGX status on system boot. Use the command
cpuid | grep -i sgx | head
Install cpuid from apt if not available
sudo apt install cpuid
SGX: Software Guard Extensions supported : true
SGX_LC: SGX launch config supported : true
SGX1 supported : true
SGX2 supported : true
Only if steps upto #4 are successful, either from iDRAC or BIOS, update PRMRR Size to maximum(64G) in SGX section.
