Automotive Linux Summit & Open Source Summit Japan 2018

Operating a large cluster, a datacenter, or a distributed network involves handling a lot of secrets. In almost all cases, you have to deal with at least four types of secrets for each piece of hardware: SSH server key (or shell access key), key to bootstrap your configuration management system, disk encryption key, and maybe some per-server credentials to access other services. And most of the time, these keys have to be set up before your configuration management kicks in, making the automation of this process more difficult.

This talk presents an approach that combines hardware support and little cryptography to deal with the above issues and unify and simplify secret management for your hardware fleet.
