 MedMon: A Novel Device for Monitoring Medical Device Security

Princeton Docket # 12-2789-1

Rapid advances in personal healthcare systems based on implantable and wearable medical devices promise to greatly improve the quality of diagnosis and treatment for a range of medical conditions. However, the increasing programmability and wireless connectivity of medical devices also open up opportunities for malicious attackers. Unfortunately, implantable/wearable medical devices come with extreme size and power constraints, and unique usage models, making it infeasible to simply borrow conventional security solutions, e.g., encryption, from general-purpose or even other embedded computing systems.

Researchers at Princeton University and Purdue University have developed a general framework for securing medical devices based on wireless channel monitoring and anomaly detection. This technology monitors all wireless communication to and from these medical devices and uses a multilayered anomaly detection methodology to identify potentially malicious transactions.  Security analysis shows that the proposed defenses, used passively by notifying the user or actively by jamming the malicious packets, have the potential to mitigate the security risks associated with personal healthcare systems. Additionally, this technology is backward-compatible with existing medical devices and, hence, does not need any hardware or software modifications.
