Continuous Analyte Sensor Proximity Pairing for Low-Power Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication protocols between analyte sensors and display devices in diabetes management systems are vulnerable to security threats, leading to potential data integrity issues, privacy breaches, and resource inefficiencies due to high power advertisements that can be intercepted by malicious devices, causing congestion and unnecessary authentication processes.
Innovation Solution
Implementing proximity pairing techniques with low power general advertisements and secondary identifiers, along with whitelist advertisements for reconnections, to secure wireless connections and reduce resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a continuous analyte sensor system uses wireless communication for data transmission, then patient comfort and ease of operation are improved, but the system becomes more vulnerable to unauthorized access and data theft
Solution Approach 1:
A proximity pairing mechanism acts as an intermediary between the sensor system and external devices. The system requires devices to establish proximity-based pairing through authenticated connections before allowing data transmission, creating a security buffer that maintains wireless convenience while blocking unauthorized access attempts
2Reliability
If the sensor system implements comprehensive security protocols for wireless communication, then security against unauthorized access is improved, but device complexity and power consumption increase
Solution Approach 1:
Security measures are applied locally and selectively rather than uniformly across all communications. The system implements proximity-based authentication and encrypted connections only when devices are in close proximity and attempting to access sensor data, while allowing other communications to proceed with minimal security overhead
3Reliability
If the sensor system implements comprehensive security protocols for wireless communication, then security against unauthorized access is improved, but power consumption increases
Solution Approach 1:
Security protocols are activated periodically and conditionally rather than continuously. The system performs proximity detection and authentication checks at specific intervals when communication attempts are detected, allowing the sensor to enter low-power states between security checks and reducing overall power consumption
4Adaptability or versatility
If the sensor system allows wireless connectivity for remote monitoring, then ease of operation and monitoring capability are improved, but the risk of data theft and unauthorized access increases
Solution Approach 1:
A proximity pairing authentication system serves as an intermediary layer between wireless connectivity and data access. The system establishes secure, authenticated communication channels only for devices that have verified proximity and identity, enabling remote monitoring capabilities while blocking data theft attempts through unauthenticated devices

AI summary
Techniques and protocols for facilitating wireless secure communications between a sensor system and one or more other devices are disclosed. In certain embodiments, the techniques and protocols include secure proximity pairing techniques with reduced power. A method for pairing an analyte sensor system and one or more display devices includes broadcasting, from the analyte sensor system, for an initial connection, a low power general advertisement including an indication indicating the low power general advertisement is for proximity pairing. The method includes receiving, from a first display device, a connection request message in response to the low power general advertisement; performing an authentication procedure with the first display device; and pairing and bonding with the first display device based on successful authentication with the first display device.
