Device attestation: Past, present, and future
Orlando Arias, Fahim Rahman, Mark Mohammad Tehranipoor, Yier Jin · 2018
In recent years we have seen a rise in popularity of networked devices. From traffic signals in a city's busiest intersection and energy metering appliances, to internet-connected security cameras, these embedded devices have become entrenched in everyday life. As a consequence, a need to ensure secure and reliable operation of these devices has also risen. Device attestation is a promising solution to the operational demands of embedded devices, especially those widely used in Internet of Things and Cyber-Physical System. In this paper, we summarize the basics of device attestation. We then present a summary of attestation approaches by classifying them based on their functionality and reliability guarantees they provide to networked devices. Lastly, we discuss the limitations and potential issues current mechanisms exhibit and propose new research directions.
