Abstract

Nowadays, an important issue in the IoT landscape consists of enabling the dynamic instauration of interactions among two or more objects, operating autonomously in a distributed and heterogeneous environment, which participate in the enactment of accountable cross-organization business processes. In order to achieve the above goal, a decentralized and reliable approach is needed. Here, we propose a solution based on physical unclonable function (PUF) and blockchain technologies that represent the building blocks of the devised IT infrastructure. The core of the authentication process is based on a purposely designed circuit for the PUF bitcell, implemented in a 65 nm CMOS technology. One of the most important aspects of this work is represented by the concept of accountability node, an element inspired to a blockchain 3.0 masternode. This is the key element of the proposed architecture, acting as the main interface for cooperating services and IoT objects which relieve the users/objects from the burden of having to directly interact with the blockchain.
