Examining the factor's influencing IoT-blockchain based secure transmission services

Area of Science:

• Cybersecurity
• Distributed Systems
• Internet of Things (IoT)

Background:

• Traditional Internet of Things (IoT) security models exhibit deficiencies in architectural validation and user-centric evaluation.
• Existing models often result in compromised trust, data integrity, and operational transparency in IoT systems.
• There is a critical need for robust security frameworks to manage and transmit data securely within IoT ecosystems.

Purpose of the Study:

• To propose and evaluate a novel blockchain-based architectural framework for secure data transmission and management in Internet of Things (IoT) systems.
• To address the limitations of traditional IoT security by introducing a user-informed, decentralized approach.
• To enhance trust, data integrity, and operational transparency in IoT environments.

Main Methods:

• A mixed-method approach was employed, integrating conceptual modeling with subjective evaluations.
• Thirty-two domain experts from development, administration, and IoT service delivery sectors participated in the evaluation.
• The framework was validated using an operational case scenario with real-world transmission flows.

Main Results:

• The Blockchain Security Service and Transmission Nodes demonstrated high effectiveness in security, data integrity, and reliability.
• Inspection Nodes yielded varied perceptions, indicating specific areas for future enhancement.
• The multi-metric evaluation framework incorporated integrity, latency, scalability, and privacy.

Conclusions:

• The proposed blockchain-based framework significantly enhances security and reliability in IoT data transmission.
• The user-informed assessment model and architectural breakdown offer practical insights for decentralized IoT development.
• The study provides a foundation for building more trustworthy and performant decentralized IoT systems.
