Security Belt for Wireless Implantable Medical Devices

Area of Science:

• Biomedical Engineering
• Cybersecurity
• Wireless Communication Systems

Background:

• Wireless implantable medical devices (IMDs) are vulnerable to security threats.
• Existing non-secure systems require enhanced protection for reliable communication.
• Power consumption is a critical factor for IMD longevity.

Purpose of the Study:

• To propose a new protective design for secure wireless IMD communication.
• To enhance physical layer security in IMD transmissions.
• To reduce power consumption and extend the battery life of IMDs.

Main Methods:

• Developed an external wearable protector (belt) with sophisticated transceiver antennas.
• Implemented random switching of beam-focused multi-antennas for transmissions to the IMD.
• Utilized multi-jammer switching with MRC combining or majority-rule based receiving for transmissions from the IMD.

Main Results:

• The proposed design provides enhanced security for wireless IMD communication.
• Effective full duplex transmissions are achieved with the integrated antenna system.
• Reduced power consumption was observed, potentially prolonging IMD battery life.

Conclusions:

• The novel wearable protector offers a viable solution for securing wireless IMD systems.
• The system is compatible with existing non-secure infrastructure.
• This approach improves both the security and operational efficiency of IMDs.
