Why Intel’s SGX-based Attestation is Questionable at Best

Affected Intel CPUs

List of Intel SGX CPUs vulnerable to the ÆPIC Leak

The TEA Project Uses TPM Chips for its Protected Enclaves

  • The actual enclave provided by Intel SGX CPUs is inadequate, with only a small portion of RAM set aside to function as the enclave.
  • SGX standards are always governed by Intel and are closed sourced. Intel goals with SGX will always align with their business objectives, such as deciding to discontinue SGX for their consumer-focused processors. Companies that rely on SGX to furnish protected enclaves for their infrastructure have to deal with the fall out of any decisions made by Intel.
