Ensuring Software Integrity in IoT Devices

Chris Echard

This paper will review the available literature covering topics relevant to ensuring software integrity of the boot image and running code in networked devices. The paper will focus on hardware devices defined as IoT (Internet of Things) in the consumer space. Software-only (virtual) devices will also be discussed. Topics reviewed will include trusted anchor concepts and technologies, chain of trust and validation of code integrity, as well as the technologies which support them, such as PKI (public key infrastructure), secure storage and mutable and immutable identities.
