They Can Hear Your Heartbeats: Non-Invasive Security for Implantable Medical Devices

Wireless communication has become an intrinsic part of modern Implantable Medical Devices (IMDs). Recent work, however, has demonstrated that wireless connectivity can be exploited to compromise the confidentiality of IMDs' transmitted data or to send unauthorized commands to IMDs - even commands that cause the device to deliver an electric shock to the patient. The key challenge in addressing these attacks stems from the difficulty of modifying or replacing already-implanted IMDs. Thus, in this paper, the authors explore the feasibility of protecting an implantable device from such attacks without modifying the device itself. They present a physical-layer solution that delegates the security of an IMD to a personal base station called the shield.
