Establishing a root-of-trust is a key early step in
establishing trust throughout the lifecycle of a device, notably by
attesting the running software. A key technique is to use
hardware security in the form of specialised modules or
hardware functions such as TPMs. However, even if a device
supports such features, other steps exist that can compromise the
overall trust model between devices being manufactured until
decommissioning. In this paper, we discuss how blockchains, and
smart contracts in particular, can be used to harden the overall
security management both in the case of existing hardwareenhanced security or when only software attestation is possible.
