Security Challenges and Solutions for Closed-Loop Artificial Pancreas Systems

This work presents security solutions related to multi-sensor closed-loop artificial pancreas (AP) systems. The proposed AP system is built on a heterogeneous platform incorporating a smartphone, activity sensors, a glucose monitor, an insulin pump, a laptop hosting the multi-variable control algorithm and a cloud server. Developing a secure AP system is essential for mass adoption among diabetes patients. However, various communication interfaces and dynamics among the AP components result in multiple security vulnerabilities and intrusion points. We first identify the threats related to both AP data communication and AP data storage. Then, we propose several cryptography and authentication measures to address the threats related to the man-in-the-middle attacks.
