Enabling Decentralised Identifiers and Verifiable Credentials for Constrained IoT Devices using OAuth-based Delegation

Dmitrij Lagutin, Yki Kortesniemi, Nikos Fotiou and Vasilios A. Siris

Decentralised identiﬁers (DIDs) and veriﬁable credentials (VCs) are upcoming standards for self-sovereign privacy preserving identiﬁers and authorisation, respectively. This focus on privacy can help improve many services and open up new business models, but using DIDs and VCs directly on constrained IoT devices can be problematic due to the management and resource overhead. This paper presents an OAuth-based method to delegate the processing and access policy management to the Authorisation Server thus allowing also systems with constrained IoT devices to beneﬁt from DIDs and VCs.
