Abstract
Tracking component configuration is provided. A central gateway is in communication with ECUs over one or more vehicle buses. The central gateway generates a first digest of first software updates installed to the ECUs, the first digest including a manifest of changes performed to the ECUs and a first hash of a subset of the first software updates. A signature is embedded into the first digest, the signature including a first digest hash of the first digest. The first digest is maintained to a non-transitory storage of the central gateway as a non-reputable record of the installation of the software updates.
