This error indicates that the OS or BIOS microcode version is outdated and can’t perform the SGX attestation with the Fireblocks server.

Resolution

Make sure the threads/processor, and hyperthreading (HT) are disabled and that SGX, DCAP, and FLC is enabled.

To verify whether HT is enabled, run the following command:

hostname# lscpu | grep Thread

This command should output:

Thread(s) per core: 1

To verify the microcode version, run the following command:

# cat /proc/cpuinfo | grep -E "model name|microcode"
# dmesg | grep microcode
# dpkg -l | grep intel-microcode
