Design and Implementation of a Central-Controllable and Secure Multicast System Based on Universal Identifier Network

Area of Science:

• Computer Science
• Network Architecture
• Cybersecurity

Background:

• Increasing network demands necessitate evolving Internet architecture beyond original designs.
• Universal Identifier Network (UIN) architecture offers enhanced mobility, security, and reliability.
• Growing demand for group communication, especially with IoT, highlights limitations in current multicast schemes.

Purpose of the Study:

• To propose a Central-Controllable and Secure Multicast (CCSM) system built upon the UIN architecture.
• To address security vulnerabilities and management difficulties inherent in open-group multicast models.
• To achieve improved mobility support, security, scalability, and controllability in multicast services.

Main Methods:

• Redesigned multicast service procedures: registration, join/leave, and routing construction/update.
• Implemented a novel group management scheme with member authentication for join/leave operations.
• Developed a central-controllable multicast routing scheme for secure router entry setup.

Main Results:

• CCSM inherits UIN's mobility and security features.
• Centralized computation and distributed multicast routing are enabled.
• CCSM demonstrates reduced multicast join delay and lower reconstruction costs compared to PIM-SM, especially in low-density scenarios.

Conclusions:

• The proposed CCSM system effectively enhances multicast communication security and efficiency.
• CCSM provides a viable solution for secure and manageable group communication in future networks.
• The system's performance advantages over PIM-SM indicate its potential for practical deployment.
