| Description | Despite of their increasing popularity, Internet of Things (IoT) platforms are still suffering from major security problems, particularly during communications between the IoT devices. Indeed, these devices are commonly prone to malicious attacks and require prior mutual authentication to guarantee the confidentiality and security of data being shared as well as a proper network operation. In order to deal with this issue, several researchers have proposed the use of the emergent blockchain paradigm, which has emerged as a key technology that will transform the way in which information will be shared. As this paradigm is facing scalability and flexibility problems, the use of multi-agents systems has been adopted in recent works. However, current solutions are using agents for the rudimentary role of data collection only. In this paper, we propose to secure the IoT platform with a multilevel blockchain system (MBS) where the speed and flexibility of blockchain transactions are enforced by mobile agents which are migrating throughout the IoT network. The simulations of our solution through the Hyperledger Fabric are showing relevant results in terms of response time and energy consumption. |
