Highlights 🎢
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.

Vitalik touched on the fact that modern computing increasingly divides tasks between flexible but less efficient ‘glue’ components and highly specialised, efficient ‘coprocessor’ components, offering advantages in terms of performance, security and accessibility.
