Footsteps in the fog: Certificateless fog-based access control

The proliferating adoption of the Internet Things (IoT) paradigm has fuelled need for more efficient and resilient access control solutions that aim to prevent unauthorized resource access. majority existing works in this field follow either a centralized approach (i.e. cloud-based) or an architecture where IoT devices are responsible all decision-making functions. Furthermore, resource-constrained nature most make securing communication between these cloud using standard cryptographic difficult. In paper, we propose distributed core components fog nodes cloud. To facilitate secure communication, our utilizes Certificateless Hybrid Signcryption scheme without pairing. We prove effectiveness by providing comparative analysis its performance comparison commonly used cloud-based architectures. Our implementation uses Azure – commercial platform, Keycloak open-source demonstrate real-world applicability. Additionally, measure adopted encryption on two types further emphasize applicability proposed architecture. Finally, experimental results coupled with theoretical proves security approach.
