Information within systems can be extracted through side-channels; unintended communication channels that leak information. The concept of side-channel sensing is explored, in which sensor data is analysed in non-trivial ways to recover subtle, hidden or unexpected information. Practical examples of side-channel sensing are well known in domains such as cybersecurity (CYB), but are not formally recognised within the domain of medical diagnostics and monitoring (MDM). This article reviews side-channel usage within CYB and MDM, identifying techniques and methodologies applicable to both domains. We establish a systematic structure for the use of side-channel sensing in MDM that is comparable to existing structures in CYB, and promote cross-domain transferability of knowledge, mindsets, and techniques.

侧通道传感：利用侧通道为医疗诊断和监测提取信息

系统内的信息可以通过侧信道提取；泄露信息的意外通信渠道。探索了侧信道感测的概念，其中以非平凡的方式分析传感器数据以恢复微妙的、隐藏的或意外的信息。侧信道感测的实际例子在网络安全 (CYB) 等领域广为人知，但在医疗诊断和监控 (MDM) 领域并未得到正式认可。本文回顾了 CYB 和 MDM 中的边信道使用，确定了适用于这两个领域的技术和方法。我们建立了一个系统结构，用于在 MDM 中使用侧信道感知，与 CYB 中的现有结构相当，并促进知识、思维方式和技术的跨域转移。
