摘要:

可植入和可穿戴医疗设备(IWMD)被广泛用于监测和治疗越来越多的医疗状况。低功耗处理器、更复杂的固件和无线连接的进步使医疗设备的改进大大改善了治疗效果和患者的生活质量。然而,安全攻击、故障和有时的用户错误引起了人们对国际大规模毁灭性武器安全的极大关注。在这项工作中,我们提出了一个硬件/软件一种用于改进IWMD的安全性的(硬件/软件)框架,其中,使用一组安全规则和规则检查机制来监视外部状态(由IWMD感测的患者的生理参数)和IWMD的内部状态(微控制器的I/O活动)来推断可能由用户错误、软件错误或安全攻击触发的不安全操作。我们讨论了如何实现这种方法的背景下,人工胰腺与无线连接,并实现了一个原型,以证明其有效性,提高安全性在适度的开销。

英文摘要:

Implantable and wearable medical devices (IWMDs) are widely used for the monitoring and therapy of an increasing range of medical conditions. Improvements in medical devices, enabled by advances in low-power processors, more complex firmware, and wireless connectivity, have greatly improved therapeutic outcomes and patients' quality-of-life. However, security attacks, malfunctions and sometimes user errors have raised great concerns regarding the safety of IWMDs. In this work, we present a HW/SW (Hardware/Software) framework for improving the safety of IWMDs, wherein a set of safety rules and a rule check mechanism are used to monitor both the extrinsic state (the patient's physiological parameters sensed by the IWMD) and the internal state of the IWMD (I/O activities of the microcontroller) to infer unsafe operations that may be triggered by user errors, software bugs, or security attacks. We discuss how this approach can be realized in the context of a artificial pancreas with wireless connectivity and implement a prototype to demonstrate its effectiveness in improving safety at modest overheads.
