Blockchain-Based Self-Sovereign Identity in 6G Non-Public Networks: Enhanced Security in Industrial Cyber-Physical Systems
Abdullah Aydeger, Engin Zeydan · 2024
The industrial sector’s digital transformation under Industry 4.0 necessitates robust, scalable, and secure communication frameworks. 6G technology, particularly its nonpublic network (NPN) configurations, offers promising solutions for industrial cyber-physical systems (ICPS). However, security and privacy remain significant challenges, especially concerning identity management in these networks. This paper proposes the integration of blockchain-based Self-Sovereign Identity (SSI) within 6G NPNs as a novel approach to enhance security and data privacy. We explore how this combination can provide decentralized identity management, reduce reliance on centralized authorities, and increase trustworthiness within industrial networks. The paper also examines real-world scenarios and provides a detailed analysis of deployment models, highlighting the potential benefits and challenges of integrating blockchain-based SSI into 6G networks.
