Game Theory Based Security in Wireless Body Area Network with Stackelberg Security Equilibrium

Area of Science:

• Biomedical Engineering
• Computer Science
• Network Security

Background:

• Wireless Body Area Networks (WBANs) offer significant potential in healthcare for improving patient outcomes and service value.
• Current WBAN systems face challenges in real-time patient response and maintaining high security due to intermittent connectivity.
• Monitoring patient physiological data in WBANs raises critical security concerns regarding data integrity and privacy.

Purpose of the Study:

• To propose a novel security mechanism for Wireless Body Area Networks (WBANs) in healthcare applications.
• To address the limitations of existing WBAN security protocols in protecting sensitive patient health information.
• To enhance the overall security posture and reliability of patient monitoring systems within WBANs.

Main Methods:

• Introduction of a Game Theory with Stackelberg Security Equilibrium (GTSSE) framework for WBAN security.
• Modeling the interaction between network players, with a designated 'position authority' as the organizer.
• Experimental evaluation of the proposed approach based on security ratio, system flexibility, energy consumption, and information loss.

Main Results:

• The GTSSE mechanism effectively considers all participating players in the security equilibrium.
• Experimental results demonstrate a considerable improvement in the security ratio for patient health information.
• The proposed approach shows enhanced system flexibility and manages energy consumption and information loss rates.

Conclusions:

• Game Theory with Stackelberg Security Equilibrium (GTSSE) provides a robust solution for enhancing security in healthcare WBANs.
• The GTSSE approach offers a significant improvement in securing patient data compared to existing methods.
• This framework contributes to more reliable and secure remote patient monitoring systems.
