Blockchain Enabled Anonymous Privacy-Preserving Authentication Scheme for Internet of Health Things.

Area of Science:

• Computer Science
• Cybersecurity
• Healthcare Technology

Background:

• The Internet of Health Things (IoHT) integrates smart devices for real-time health monitoring, raising concerns about patient data confidentiality and privacy.
• Existing IoHT systems face security challenges, necessitating robust authentication mechanisms to protect sensitive health information.
• The increasing role of IoHT in the Internet of Things highlights the urgent need for secure communication protocols.

Purpose of the Study:

• To propose a novel blockchain-based privacy-preserving authentication scheme for the Internet of Health Things (IoHT).
• To develop a secure handover authentication mechanism for seamless multi-doctor communication and to prevent malicious behavior.
• To enhance patient data confidentiality and privacy in IoHT networks without relying on a trusted third party.

Main Methods:

• A novel blockchain-based privacy-preserving authentication scheme is proposed.
• A secure handover authentication mechanism is developed to manage multi-doctor scenarios and revoke malicious professionals.
• Performance analysis comparing the proposed scheme against existing state-of-the-art authentication methods.

Main Results:

• The proposed authentication scheme demonstrates resistance to various security attacks.
• The scheme achieves efficient patient authentication without a trusted entity.
• The system offers lower computational, communication, and storage costs compared to existing schemes.

Conclusions:

• The novel blockchain-based authentication and handover scheme significantly improves IoHT communication security.
• The proposed solution is resistant to attacks and outperforms existing methods in efficiency.
• The scheme has practical applicability, contributing to enhanced security in IoHT networks.
