Résumé
Security is one of the major challenges of the Internet of Things (IoT). In an IoT network, data are processed and exchanged without human intervention. Because of this autonomy, objects must authenticate each other as well as to ensure the integrity of the exchanged data. An efficient authentication scheme allows to protect the network against several attacks. Several IoT authentication schemes have already been proposed but they are mostly ineffective and sometimes have limitations. This work proposes a new mutual authentication scheme for IoT based on digital signatures, the Physical Unclonable Functions (PUF) and the blockchain technology. The Global Assessment and analyses show that our new protocol gives more resistance to different types of attacks, and that it also provides a better performance in terms of computing load although it requires fewer storage resources.
