The Update Framework

A framework for securing software update systems

The Update Framework (TUF) helps developers maintain the security of a software update system, even against attackers that compromise the repository or signing keys. TUF provides a flexible framework and specification that developers can adopt into any software update system.

TUF is hosted by the Linux Foundation as part of the Cloud Native Computing Foundation (CNCF) and is used in production by companies such as Docker, DigitalOcean, Flynn, LEAP, Kolide, Cloudflare, and VMware. A variant of TUF called Uptane is widely used to secure over-the-air updates in automobiles.
