Digital Sensors and Sensor Sysstems


Abstract: The Internet of Things (IoT) has finally made its way into people’s daily lives. Multiple connected objects are present in many markets. Their rapid adoption is due to the fact that IoT applications are developing rapidly and are easily deployed. However, these applications present several security challenges, although they are based on existing network technologies, which are already more or less secure. These challenges can be broadly classified as identification, authentication, jamming, cloning, privacy, etc. To face these challenges and in the perspective of ensuring end-to-end IoT networks security, several encryption mechanisms have been adapted and widely used including public key infrastructure (PKI), AES standard and ECC (Elliptic Curve Cryptography). To correct the weaknesses and vulnerabilities that are still present, other technologies such as DLTs (Distributed Ledger Technology) have been recently adopted by the Internet of Things. This adoption is still in its infancy as there are no standards nor methods yet indicating how to manage the security of the IoT through DLTs. In this article, we review the IoT-DLT paradigm in order to identify the benefits and major challenges of the convergence of these two technologies.


Keywords: IoT, DLT, Blockchain, Security, Cloud.
