Secret Forwarding of Events over Distributed Publish/Subscribe Overlay Network.

Area of Science:

• Computer Science
• Distributed Systems
• Network Security

Background:

• Publish/subscribe systems enable asynchronous communication for large-scale, event-driven applications.
• These systems are crucial in domains like social networking and critical infrastructure.
• Existing systems face challenges with message loss and privacy violations.

Purpose of the Study:

• To propose a novel method for reliable and confidential message delivery in publish/subscribe systems.
• To address the challenges of message loss and privacy breaches in distributed environments.
• To develop a framework for dynamic broker replica allocation.

Main Methods:

• Utilizing secret sharing and replication techniques for secure key distribution.
• Implementing a framework for strategic allocation of broker replicas.
• Conducting a case study using real-world social network interaction data.

Main Results:

• Demonstrated reliable and confidential delivery of decryption keys.
• Showcased enhanced system resilience against Byzantine brokers.
• Validated the effectiveness of the proposed framework through a social network case study.

Conclusions:

• The proposed method significantly improves the security and reliability of publish/subscribe systems.
• Dynamic replica allocation optimizes performance and fault tolerance.
• The approach is effective for real-world applications like social networks.
