“…However, the introduced bit-monitoring convention applies to certain types of signals and is more suitable for occasional verification of the correctness of the A/D conversion. In the framework presented in [14], multiple hashes are generated for internal SoC signals in multiple internal stages, and are used for verifying the integrity of the signals as they propagate in the SoC. By focusing on the security of the intermediate signals in SoCs and implementing the security measures in independent security elements, this framework addresses a similar issue to that addressed in this paper.…”

Recent advances in hardware attacks, such as cross talk and covert channel based attacks, expose the structural and operational vulnerability of analog and mixed-signal circuit elements to the introduction of malicious and untrustworthy behaviour at run-time, potentially leading to adverse physical, personal, and environmental consequences.One untrustworthy behaviour of concern, is the introduction of abnormal/unexpected frequencies to the signals at the analog/ digital interface of a SoC, realised through intermittent bit-flipping or stuck-at-faults in the middle and lower bits of these signals.In this paper, we study the impact of these actions and propose integrity monitoring of signals of concern based on analysing the temporal and arithmetic relations between their samples. This paper presents a hybrid software/ hardware machine-learning based framework that consists of two phases; a run-time monitoring phase, and a trustworthiness assessment phase. The framework is evaluated with three different applications and its effectiveness in detecting the untrustworthy behaviour of concern is verified. This framework is device, application, and architecture agnostic, and relies only on analysing the output of the analog front-end, allowing its implementation in SoCs with on-chip and custom analog front-ends as well as those with outsourced and commercial off-the-shelf (COTS) analog front-ends.

“…The FDA has released numerous reports on changing patient's health data by modifying medical device hardware [57,58]. In recent work, researchers presented an HT attack on the bacillus calmette guerin (BCG) scale [59]. They injected a malicious payload that modifies the logic of an XOR gate on the input bus.…”

The recent advancements in computing systems and wireless communications have made healthcare systems more efficient than before. Modern healthcare devices can monitor and manage different health conditions of the patients automatically without any manual intervention from the medical professionals. Additionally, the use of implantable medical devices (IMDs), body area networks (BANs), and Internet of Things (IoT) technologies in healthcare systems improve the overall patient monitoring and treatment process. However, these systems are complex in software and hardware, and optimizing between security, privacy, and treatment is crucial for healthcare systems as any security or privacy violation can lead to severe effects on patients' treatments and overall health conditions. Indeed, the healthcare domain is increasingly facing security challenges and threats due to numerous design flaws and the lack of proper security measures in healthcare devices and applications. In this paper, we explore various security and privacy threats to healthcare systems and discuss the consequences of these threats. We present a detailed survey of different potential attacks and discuss their impacts. Furthermore, we review the existing security measures proposed for healthcare systems and discuss their limitations. Finally, we conclude the paper with future research directions toward securing healthcare systems against common vulnerabilities. CCS Concepts: • General and reference → Surveys and overviews; • Security and privacy → Systems security; • Applied computing → Health care information systems.
