Hyperledger Fabric Access Control System for Internet of Things Layer in Blockchain-Based Applications

Area of Science:

• Computer Science
• Cybersecurity
• Distributed Systems

Background:

• Blockchain applications are expanding into supply chain, healthcare, and finance.
• Internet of Things (IoT) devices are crucial for data collection in these applications.
• Establishing trust and secure access for IoT devices is a significant challenge.

Purpose of the Study:

• To integrate Hyperledger Fabric blockchain with IoT devices.

• To establish a root of trust for IoT devices on ARM64 architecture.

Main Methods:

• Utilized Hyperledger Fabric for its security features like encryption and cryptography.
• Developed an ABAC mechanism using only Hyperledger Fabric components.
• Adapted Hyperledger Fabric for ARM64 architecture by building executable binaries and Docker images.
• Deployed and ran a fabric node in native mode on a Raspberry Pi 4 Model B (ARM64).

Main Results:

• Successfully generated and evaluated Hyperledger Fabric executable binaries for ARM64 architecture.
• Demonstrated the feasibility of running Hyperledger Fabric nodes natively on IoT devices.
• Validated the effectiveness of the implemented ABAC mechanism for IoT access control.

Conclusions:

• The integration of Hyperledger Fabric with IoT devices provides a secure framework for access control.
• The study successfully established a root of trust for IoT devices on the ARM64 architecture.
• This research paves the way for secure and trusted IoT deployments in various fields.
