  1. P.1 — Title slide. "Design and Basic Evaluation of Virtual IPv4 based CYPHONIC adapter" presented at IMCIC 2022
  2. P.2 — Presentation outline covering network security, CYPHONIC concept, issues, objective, proposed system, evaluation, and conclusions
  3. P.3 — Comparison of perimeter security model and zero-trust security model. Cloud and IoT spread drives demand for zero-trust
  4. P.4 — Requirements for zero-trust security model. Direct device connection needed for secure end-to-end communication across diverse network environments
  5. P.5 — Concept of CYPHONIC (CYber PHysical Overlay Network over Internet Communication). Supports inter-connectivity, seamless mobility, and secure authentication
  6. P.6 — Issues of conventional CYPHONIC. General nodes like IoT and embedded devices cannot install CYPHONIC programs
  7. P.7 — Objective: Proposal of virtual IPv4 based CYPHONIC adapter to perform CYPHONIC communication on behalf of general nodes
  8. P.8 — Components of CYPHONIC: CYPHONIC Node, Authentication Service (AS), Node Management Service (NMS), and Tunnel Relay Service (TRS)
  9. P.9 — Processing functions in CYPHONIC node: Signaling Module, CYPHONIC Resolver Module, and Packet Handling Module
  10. P.10 — System model of CYPHONIC node showing data flow between application, CYPHONIC Daemon, virtual/real interfaces, and the Internet
  11. P.11 — Concept of CYPHONIC adapter. Extends CYPHONIC Daemon to perform communication on behalf of general nodes and manage their information
  12. P.12 — Processing functions in CYPHONIC adapter: Signaling, Packet Handling, General Node Management, Address Configuration, and Interface Handling Modules
  13. P.13 — System model of CYPHONIC adapter showing Adapter Daemon with management and communication functions connected via two real interfaces
  14. P.14 — Sequence diagram for getting general node information: authentication, registration, and information retrieval from AS and NMS
  15. P.15 — Sequence of general node configuration: virtual IPv4 address assignment via DHCPv4, authentication, and registration for general nodes
  16. P.16 — Sequence of overlay network communication: route selection, tunnel establishment, ARP process, and data communication
  17. P.17 — Basic evaluation setup. Measuring adapter processing time and communication performance using Raspberry Pi 4 and MacBook Air
  18. P.18 — Detailed evaluation process: DNS response time and ARP response time measurement during initial communication
  19. P.19 — Results of initial communication delay. General node: 28.00ms total. Route selection is the dominant factor in processing time
  20. P.20 — Communication performance results. General node via adapter achieves 30+ Mbps throughput with minimal overhead compared to CYPHONIC node
  21. P.21 — Conclusions. Proposed system provides CYPHONIC communication capabilities to general nodes without significant overhead
