The Tragedy of the Oxide Root of Trust

Oxide’s root-of-trust key ceremony shows what careful secure-device manufacturing can look like - and how demanding it is. In a public discussion, the engineers explain their preparations and procedures, including choosing a YubiHSM 2, printing key shares on a dot-matrix printer that was later destroyed, documenting each operation, and correcting an earlier misuse of tamper-evident packaging. Their approach draws on established practices such as IANA’s DNSSEC key-signing ceremonies. Oxide’s transparency is especially valuable in an industry where companies often conceal their processes or rely on provisioning vendors without understanding what happens behind the scenes.

The central argument is that Oxide’s achievement is both exemplary and troubling: the team did things right, but doing them required substantial expertise, time, and resources. A key ceremony is only the first step; code signing, credential provisioning, secure manufacturing, and device lifecycle management remain. Small companies entering hardware development cannot reasonably be expected to master specialized equipment and complex procedures on their own. The path to better device security therefore cannot depend only on urging companies to work harder. Hardware makers should share their methods, while semiconductor companies must improve the products, tools, and documentation that help customers implement secure boot, identity, and attestation. The goal is to make sound security practical for organizations with fewer resources, not just well-funded teams.
