CYPHONIC Adapter: Enabling Secure P2P Connectivity for Diverse IoT Devices

Peer-to-Peer (P2P) communication emerges as a potent paradigm in distributed processing models. However, network accessibility challenges and inherent limitations in existing solutions have impeded the full realization of P2P's potential. To address these issues, we've developed CYber PHysical Overlay Network over Internet Communication (CYPHONIC), an innovative solution enabling P2P-based direct device-to-device communication while ensuring robust zero-trust security. Additionally, we introduce the concept of a gateway device equipped with a CYPHONIC adapter to cater to conventional devices, often referred to as general nodes. Our paper focuses on implementing a remote camera monitoring solution, providing secure access to surveillance cameras. We aim to demonstrate that our overlay network seamlessly connects all CYPHONIC clients, including general nodes. We also present a comprehensive case study centered on remote camera monitoring. This case study showcases the effortless connectivity enabled by our overlay network, highlighting how CYPHONIC clients, including general nodes, can efficiently interconnect.
