Abstract
En 中文
With medical devices and Internet-of-Things (IoT) becoming increasingly connected, e-health applications have been widely developing. However, security of both sensitive health information and critical device settings is a significant concern. Due to the intrinsic limitations of many medical devices, including low power and limited computational resources, security and device performance can be difficult to balance - especially for implanted devices, as implanted devices require a surgical procedure to replace the device or battery. In this work we propose a system model for e-health applications with consideration of heterogeneous medical devices, in terms of battery capacity and computational ability. In addition, different attacks are considered in the proposed system model. A case study is presented to show that the proposed system model can support heterogeneous medical devices with varying power and resource constraints. The case study demonstrates that it is possible to significantly reduce the overhead for security on power-constrained devices based on the proposed system model.
