| description | The popularity of the <i>Internet of Things</i> (IoT) and <i>Industrial IoT</i> (IIoT) has caused a rapid increase in connected entities and exposed its lack of adequate <i>Identity Management</i> (IdM). Traditional IdM systems are highly dependent on central authorities; any failure can potentially compromise the entire system. To eliminate the drawback of central authorities and evolve IdM systems to meet increasingly stringent security requirements, the <i>Decentralized Identification</i> approach has been proposed. This approach often relies on blockchain technology to provide a secure and tamper-proof method of managing and verifying identities. Therefore, this article investigates the capabilities of blockchain-based decentralized identification for the IoT domain, with an emphasis on the heterogeneity of online devices. It describes a number of features and specifications of decentralized identification with a specific focus on <i>Self-Sovereign Identity</i> (SSI), a model in which entities own their identities. The article concludes with a discussion of technical aspects as well as potential obstacles and constraints to the implementation of decentralized identification in the context of the Internet of Things. |
