DM-Verity Rootfs Protection
FOSDEM 2023

Device-Mapper’s “verity” target provides transparent integrity checking of block devices using a cryptographic digest provided by the kernel crypto API. This target is read-only.

This presentation will illustrate how to integrate dm-verity with A/B booting as u-boot as used in project opencritis.org.

Speakers: Frank Rehberger
