LASII : Lightweight Authentication Scheme using IOTA in IoT Platforms

Internet of Things (IoT) has emerged as a key technology with a large spectrum of applications in various fields. However, it still faces several security challenges, in particular authentication-related challenges. Efficient “traditional” authentication solutions are often centralized, which cannot meet all the IoT requirements, especially in term of scalability. This paper proposes a new authentication scheme using the promising distributed ledger technology “IOTA” and the Masked Authenticated Messaging module. The proposed scheme is implemented, simulated and compared to other existing schemes. Its effectiveness is evaluated according to the IoT requirements. The implementation was done In IOTA v1 where IRI played an important role as a coordinator to verify transactions and interact with client library, in the next publication IOTA v2 will be implemented benefiting from Coordicide with the elimination of the coordinator in order to provide a benchmark showing the differences between IOTA v1 and IOTA v2.
