Abstract. Implantable medical devices (IMDs), such as pacemakers, implanted cardiac de brillators and neurostimulators are medical devices implanted into patients' bodies for monitoring physiological signal and performing medical treatments. Many IMDs have built-in radio modules to facilitate wireless data collecting and reprogramming by external programmers. The wireless communication brings significant conveniences for advanced applications such as real-time and remote monitoring but also introduces the risk of unauthorized wireless access. The absence of effective access control mechanisms exposes patients' life to cyberattacks. In this paper, we present a lightweight and universally applicable access control system for IMDs. By leveraging Physically Obfuscated Keys (POKs) as the hardware root of trust, provable security is achieved based on standard cryptographic primitives while attaining high energy e ciency. In addition, barrier-free IMD access under emergent situations is realized by utilizing the patient's biometrical information. We evaluate our proposed scheme through extensive security analysis and a prototype implementation, which demonstrate our work's superiority on security and energy e ciency.
