Blockchain-Based Infrastructure to enable Trust in IoT environment

Nowadays, with the further development of telecommunication, IoT technology has become a concrete reality of everyday life. However, the widespread adoption of such technologies is sharply limited by Trust concerns for IoT devices, in terms of reliability, traceability, integrity, and privacy of the data. The lack of digital traceability increases the market time for IoT environment adoption. Contemporary Blockchain has been identified as one of the most promising technology to grant data security and reliability. The recent developments of such technologies have led to the possibility to build a shared, distributed, trustful, and autonomous infrastructure system making it hopeful for IoT systems. The constrained resources of low-level devices used in the IoT networks represent a significant hindrance to the integration of Blockchain and IoT technologies. Different kind of light protocols for IoT communication and secure authentication has been proposed to this end; some of this requires the slightest effort for resources integration. In this paper, an audit system for metrological traceability in a distributed measurement system is proposed. The system is based on Blockchain technology and Physical Unclonable Functions (PUF) access security protocol.
