Multifactor Authentication for Smart Emergency Medical Response Transporters

Area of Science:

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

Background:

• Telehealth IoT infrastructure is critical for modern healthcare delivery.
• Securing connected medical devices, especially during patient transport, presents unique challenges.
• Vulnerabilities in transit can lead to data breaches and compromise patient safety.

Purpose of the Study:

• To propose a robust multifactor authentication scheme for telehealth IoT systems during patient transit.
• To enhance the security of ambulance and air ambulance communication networks.
• To prevent unauthorized access and cyberattacks on mobile healthcare infrastructure.

Main Methods:

• Development of a novel multifactor authentication scheme tailored for mobile telehealth scenarios.
• Integration of physical unclonable functions (PUFs) for secure device authentication and key exchange.
• Application and validation of the scheme within an ambulance transport simulation.

Main Results:

• The proposed scheme effectively authenticates devices and facilitates secure key exchange in transit.
• Formal and informal security analyses confirm the scheme's resilience against various cyber threats.
• Demonstrated protection against common attacks targeting connected medical devices.

Conclusions:

• The multifactor authentication scheme significantly improves the security of telehealth IoT during patient transport.
• PUF-based authentication offers a promising solution for securing mobile healthcare environments.
• The findings contribute to safer and more reliable telehealth services, particularly in emergency medical transport.
