Three-Factor Fast Authentication Scheme with Time Bound and User Anonymity for Multi-Server E-Health Systems in...

Area of Science:

• Computer Science
• Electrical Engineering
• Telecommunications

Background:

• 5G technology enables high-speed, low-latency wireless sensor networks (WSNs) crucial for Internet of Things (IoT) applications.
• Electronic healthcare (e-health) systems leverage WSNs for efficient data management, but face security and privacy challenges with increasing device numbers.
• Existing single-server authentication models incur high database costs and are vulnerable to security breaches.

Purpose of the Study:

• To propose a novel three-factor fast authentication scheme for multi-server e-health systems within 5G-enabled WSNs.
• To enhance security and user privacy while ensuring efficient and reliable data transmission in e-health applications.
• To address the limitations of existing authentication methods, including database costs and security vulnerabilities.

Main Methods:

• Developed a three-factor authentication protocol integrating biometrics, password, and smart card for robust security.
• Implemented user anonymity and time-bound authentication features to protect sensitive healthcare data.
• Designed a multi-server architecture to distribute network load and reduce database management costs.

Main Results:

• The proposed scheme provides a high-security environment for e-health communication, preserving user anonymity.
• Fast authentication ensures efficient data transfer, benefiting healthcare service delivery.
• Security proofs and performance analysis confirm the protocol's resistance to various attacks and its cost-effectiveness.

Conclusions:

• The novel authentication scheme offers a secure, private, and efficient solution for 5G-based e-health systems using WSNs.
• The multi-server approach effectively mitigates database costs and simplifies network management.
• This research contributes to advancing secure and reliable e-health services in the era of 5G and IoT.
