Abstract
In the era of Edge Computing, Internet of Things(IoT) devices connect and communicate
to create a network of objects that can collect information from the environment without
human intervention. While the IoT offers many benefits, it also poses several cybersecurity
risks, including the lack of detection of malicious IoT sensors, weak authorization,
and authentication protocols, and insecure management of data received from IoT devices.
Developing new solutions to enhance IoT sensors’ security to address these issues
is crucial. One crucial challenge that requires attention is the secure management and
storage of data collected from IoT devices at the Edge. Many existing solutions rely on
centralized systems vulnerable to tampering and must provide reliable data traceability
records. To address this challenge, this thesis proposes a blockchain-based architecture
for securing and managing data collected from IoT devices. By leveraging blockchain
technology, we create a distributed data storage architecture that eliminates the need
for centralized network topologies. This approach offers several advantages, including
immutability, decentralization, distributivity, enhanced security, transparency, instant
traceability, and increased efficiency through automation. Our results demonstrate that
this proposed architecture provides a high level of performance and can be used as a
scalable, massive data storage solution for IoT devices using blockchain technologies.
One significant advantage of this approach is that new IoT sensors can quickly be enrolled
and unenrolled in our architecture without retrofitting. Our system does not depend
on any specific communication protocol and can be applied to any IoT application. In
summary, our proposed architecture provides a robust and secure solution for managing
and storing data collected from IoT devices, thus enhancing the overall security of the
IoT devices in the Edge.
