The HARV-SoC comprises peripherals and the fault-tolerant HARV core, which relies on hardening strategies, such as physical and information redundancy, to meet the requirements of critical applications targeting harsh environments and reduce the propagation of errors.

The aim of this work is to present a multiparameter tool for vital signs monitoring, starting from photoplethysmographic (PPG) and electrocardiographic (ECG) signal extraction and processing. In particular, a multi-wavelength photoplethysmographic sensor is used for the prediction of heart rate and the degree of blood hemoglobin oxygenation; with a simultaneous mining of the PPG signal with the ECG signal, it is also possible to determine the value of systolic pressure, by calculating the Pulse Transit Time (PTT), that is, the time interval between the R wave of the ECG signal and the subsequent systolic peak of the PPG signal. Such algorithms have been validated using reference instruments (sphygmomanometer and pulse oximeter): the performance is promising, with an average relative error of less than 5%. Results suggest that this innovative approach to vital signs monitoring can lead to the development of an electronic device that is simple to use, low cost and non-invasive.","PeriodicalId":261827,"journal":{"name":"2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126699172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This communication paradigm arises new security challenges. Mainly, authenticity of network nodes, to let ones with malicious intent not thrive in such a network; and confidentiality, when sensitive data have to be exchanged. Most classical security techniques are not suitable to address such issues, especially in Wireless Sensor Network (WSN) where network nodes are developed using resource-constrained devices. Consequently, the scientific literature has been starting to investigate how Physically Unclonable Functions (PUFs), a unique digital identifier obtained from physical variability induced by integrated circuit manufacturing process, could be exploited to provide security mechanisms. In this paper, we present ConPHEMAP, a new lightweight PUF-based key management-scheme for point-to-point communications. The proposed scheme extends the PHEMAP protocol and inherits same properties, including flexibility since can be adopted either in the case where both nodes are provided with PUFs or when only one of them includes it. We also conducted a security analysis to verify the protocol resilience against different kinds of attacks, which proves its suitability in a heterogeneous insecure context such as WSNs.","PeriodicalId":261827,"journal":{"name":"2023 9th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126564619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The HERD experiment will provide high quality data on charged cosmic rays up to PeV energies and gamma rays above 100 MeV energies. In order to explore the capability of charge identification of nuclei up to iron, a beam test campaign was performed in 2022 at CERN to study the overall performance of the PSD. The PSD prototype is composed of 8 plastic scintillator trapezoidal bars of two different lengths. The PSD prototype was irradiated with an ion beam composed of particles of selected momentum of 150 GeV/n at CERN SPS H8 beam line. Along the beam line two 10× 10× 0.5 cm3 squared plastic scintillator tiles were also placed to monitor the beam composition and the particle fragmentation upstream and downstream the beam line.

In fact, while advanced cryptographic and security techniques such as secure multi-party computation, federated learning and root of trust are edging closer to deployment in the real world, they have largely not been adopted in the medical and healthcare domain. In this work, we argue that such adoption, enabled by stronger collaboration and deeper mutual knowledge between the healthcare and cyber security research community, is crucial for the success and safety of medical devices and sensors.
