The use of IoT devices especially sensors and actuators continue to emerge across many domains: Smart city, Smart vehicle, Smart healthcare, Smart Factory. . . and influences the way we live and act nowadays. Nevertheless, IoT networks are subject to many security concerns related to privacy, data integrity, traceability, reliability and more. Device authentication is the key stone to prevent security attacks, guarantee the efficiency of the IoT network and ensure a reliable information exchange. Many works have been done around device-to-device and user-to-device authentication protocols and different factors have been considered: RFI tags, MAC address, PUF, Unique ID, . . . all aiming to provide an efficient and secure authentication scheme that suits the heterogeneous resource constrained IoT devices. In this paper we discuss several ways of device-to-device authentication for IoT applications presented by researchers to ensure enhanced authentication protocols and key exchange mechanisms. We also highlight common challenges for these mechanisms in relation with timestamp accuracy and time synchronization which seems to be a green field for scientific researches related to IoT.
