Identity and Access Management for the Computing Continuum
The computing continuum introduces new challenges for access control due to its dynamic, distributed, and heterogeneous nature. In this paper, we propose a Zero-Trust (ZT) access control solution that leverages decentralized identification and authentication mechanisms based on Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs). Additionally, we employ Relationship-Based Access Control (ReBAC) to define policies that capture the evolving trust relationships inherent in the continuum. Through a proof-of-concept implementation, we demonstrate the feasibility and efficiency of our solution, highlighting its potential to enhance security and trust in decentralized environments.
