Using Blockchain for Enhanced Inter-MNO Authentication in B5G and 6G Networks

Year: 2025

Type: conference-paper

Abstract: This paper introduces a Blockchain-based overlay network that allows users to authenticate and access services across different MNOs without requiring prior agreements. The overlay leverages smart contracts for decentralized access control and IPFS for secure, shared storage of encrypted subscription data. A hybrid testbed using OpenAirInterface, Magma Core, Go Ethereum, and IPFS validates the system, demonstrating comparable latency, secure, and scalable cross-operator authentication---supporting flexible inter-operator collaboration in future B5G/6G networks.
