The joint research paper is titled A Cross-Domain Interoperable Authentication Framework for
5G-Enabled IoT and Fog Computing Networks

The explosive growth of 5G-enabled Internet of Things (IoT) and fog computing infrastructure leads to cross-domain authentication, interoperability, and energy-efficiency problems. The lightweight or blockchain-based authentication schemes in the literature, however, only focus on security or decentralization and do not support cross-domain adaptive session continuity.
The research contribution is a Cross-Domain Interoperable Authentication Framework (CDIA-Fog) employing the PUF-based device identity, blockchain-assisted trust evidence, adaptive key translation, and energy-aware re-authentication. The framework supports secure roaming across different fog administrative domains instead of only cross-domain authentication.
The proposed mechanism integrates hardware-based PUF identity, hash-based mutual authentication, blockchain token validation, and risk-energy adaptive re-authentication policy. Theoretical analysis under the Random Oracle Model and structural attack analysis demonstrate resilience against replay, impersonation, and man-in-the-middle attacks.
Experimental validation on Raspberry Pi IoT nodes and Intel-based fog gateways demonstrate an authentication cost of 0.0928 ms and a 1728-bit communication overhead. In ROAM environments, with respect to the hash-only and ECC-lightweight baselines, our CDIA-Fog is able to decrease re-authentication rate and long-term energy cost by about 18–23%.
The architecture is capable of providing secure cross-domain auditable key agreement, succinctly for mobile IoT–fog environments with acceptable overhead and flexible efficiency.https://pubs2.ascee.org/index.php/IJRCS/article/view/2583
