Yet another SGX vulnerability

Last week, a new invulnerability was discovered that allows you to extract the Intel SGX Fuse Key0 aka Root Provisioning Key. FK0 is unique to each chip but the key to encrypt FK0 is not unique to each chip. If attacker found the fuse encryption key (GWK, can decrpyt FK0), they can use it on every chip, as Sylvain said. Also Pratyush wrote an in-depth analysis of the breach.

Intel HW is too complex to be absolutely secure! After years of research we finally extracted Intel SGX Fuse Key0, AKA Root Provisioning Key. Together with FK1 or Root Sealing Key (also compromised), it represents Root of Trust for SGX. Here's the key from a genuine Intel CPU

  Highlights:
  - Fewer multi-slot sequences of builders were observed than a random Monte Carlo simulation would predict, with the longest sequence being 25 slots.
