Abstract

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 hardware enhanced security or when only software attestation is possible.
