Zero touch privacy preserving provisioning in an Edge-, Fog, and Cloud environment

IoT device onboarding, especially in the context of an edge-fog-cloud architecture, still has many challenges to solve. FIDO has already specified a zero-touch onboarding process called FIDO Device Onboarding (FDO) specification. In this paper, we present improvements to the FDO specification regarding performance and privacy. For privacy and security reasons, we show how the URL of the Owner Fog can be hidden from the Rendezvous Server. Further, we replaced the EPID protocol with a promising privacy-preserving protocol called AACKA. We also modified the last phase in the FDO protocol to create a performance improvement.
