Résumé

Several authentication protocols based on Physically Unclonable Functions (PUF) have been proposed to authenticate hardware devices. The preliminary steps of a PUF-based authentication protocol are to obtain and store on a remote server the reference device's identifier (known as the PUF response) by the manufacturer. This reference identifier is compared (accurately or with a small threshold) with the identifier given by the device during its normal use. However, the responses provided by a PUF are not fully stable over time and with environmental variations. Consequently, correction mechanisms have to be used to increase the PUF responses steadiness. In most of proposed correction scheme in the literature, the correction mechanisms consume more area than the PUF; hence, these solutions are unfeasible for area and cost restricted devices such as consumer items used for IoT applications (identification of items and hardware traceability). In order to provide an authentication protocol suitable for IoT, this article presents the use of preliminary PUF noise characterization before ultra-lightweight device identification. The proposed PUF-based authentication protocol, called restoration protocol, adapts the reference PUF response (store on the remote server) to the generated PUF response on the device without leaking any information to an adversary. In addition, the restoration protocol is implemented without any expensive hardware system on the device side. The workload is performed only on the server side, which has more resources. The security analysis and the experimental validation, using real PUF responses obtained from TERO-PUF, presented in this paper demonstrate the viability of the proposed protocol.
