Scalable Access Management in IoT Using Blockchain: A Performance Evaluation

The rise of the Internet of Things (IoT) implies new technical challenges such as managing a universally vast number of IoT devices. Although there are already a variety of secure management frameworks for IoT, they are based on centralized models, which limits their applicability in scenarios with a large number of IoT devices. In order to overcome those limitations, we have developed a distributed IoT management system based on blockchain.

In this paper, we compare the performance of our solution with the existing access management solutions in IoT. We study the delays and the throughput rate associated with the systems and analyze different configurations of our solution to maximize its scalability. The objective of the paper is to find out whether our solution can scale as well as the existing management systems in IoT.
