Blockchain Based Authentication and Trust Management in Decentralized Networks
Axel Moinet, Benoît Darties · 2021
In the Internet of Things (IoT), sensor networks form the basis for interactions with the environment and are seeing accelerated development. This chapter introduces the IoT challenges that we are going to examine here. These are challenges that are related to functioning, confidentiality and security. The chapter describes the concepts of authentication and integrity as well as the concepts of reputation and trust. It introduces the authors' contribution, the Blockchain Authentication and Trust Module (BATM) architecture. The chapter presents the notations used the general architecture of the BATM, and describes how BATM aims to respond to authentication needs by specifying the mechanisms that we have implemented. It explores the evaluation of BATM architecture through simulations. The chapter concludes the relevance of BATM with respect to the results obtained and also explains the possible future prospects of this work.
