T2T-MAP: A PUF-Based Thing-to-Thing Mutual Authentication Protocol for IoT

As security has always been an afterthought of innovation, the IoT (Internet Things), in general, and authentication, particular, become a serious research challenge. Although many authentication protocols have proposed literature during past decade, most them do not fulfill performance requirements. Furthermore, only very small number these can be used Thing-to-Thing (T2T) architectures, where Things autonomously authenticate each other without involving any human intervention. In this paper, we propose novel lightweight T2T mutual protocol (T2T-MAP) using PUFs (Physical Unclonable Functions). The employs technology to allow Thing uniquely identify itself infrastructure by physical randomness its circuitry. We design perform analysis show that it is secure against known attacks. Also, prove prover. Finally, implement prototype on resource-constrained devices then conduct demonstrate allows fast reasonable communication overhead, low energy consumption.
