LBSS: A Lightweight Blockchain-Based Security Scheme for IoT-Enabled Healthcare Environment.

Area of Science:

• Health Informatics
• Cybersecurity
• Internet of Things (IoT)

Background:

• The integration of Internet of Things (IoT) technology in healthcare has advanced patient care.
• However, increasing cyber threats and data breaches pose significant risks to sensitive health information.
• Ensuring a secure and reliable IoT-enabled healthcare system is a critical priority.

Purpose of the Study:

• To propose a novel security scheme, LBSS (Layered Blockchain Security Scheme), for IoT-enabled healthcare environments.
• To address the growing concerns of data integrity, secure storage, and access control in healthcare systems.
• To enhance the overall security and reliability of IoT health systems.

Main Methods:

• Implemented a three-mechanism security scheme: blockchain for transaction integrity, data distribution across multiple servers for secure storage, and an authorization test for data access.
• Prioritized healthcare data based on importance to minimize security overhead, tailoring security mechanisms to each data level.
• Utilized the NS3 package to simulate the IoT-enabled healthcare environment and evaluate the proposed scheme's performance.

Main Results:

• The proposed LBSS security scheme demonstrated superior performance compared to traditional models.
• Simulation results validated the effectiveness of the integrated security mechanisms in protecting IoT healthcare data.
• The prioritized approach to data security proved efficient in managing security overhead.

Conclusions:

• The LBSS security scheme offers a robust solution for securing IoT-enabled healthcare systems against cyber threats.
• The findings highlight the potential of combining blockchain, data distribution, and tiered access control for enhanced healthcare data protection.
• The proposed scheme provides a foundation for building more secure and trustworthy digital health platforms.
