This paper presents RespWatch, a wearable sensing system for robust RR monitoring on smartwatches with Photoplethysmography (PPG). We designed two novel RR estimators based on signal processing and deep learning. The signal processing estimator achieved high accuracy and efficiency in the presence of moderate noise. In comparison, the deep learning estimator, based on a convolutional neural network (CNN), was more robust against noise artifacts at a higher processing cost. To exploit their complementary strengths, we further developed a hybrid estimator that dynamically switches between the signal processing and deep learning estimators based on a new Estimation Quality Index (EQI). We evaluated and compared these approaches on a dataset collected from 30 participants. The hybrid estimator achieved the lowest overall mean absolute error, balancing robustness and efficiency. Furthermore, we implemented RespWatch on commercial Wear OS smartwatches. Empirical evaluation demonstrated the feasibility and efficiency of RespWatch for RR monitoring on smartwatch platforms.","PeriodicalId":130134,"journal":{"name":"Proceedings of the International Conference on Internet-of-Things Design and Implementation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128980512","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}

Meanwhile, security is seen as one of the most critical issues of low-power IoT devices even with pre-quantum public key cryptography since IoT devices have strict energy constraints and limited computational power. Thus, state-of-the-art dedicated hardware accelerators have been deployed to facilitate secure and confidential communication with well established protocols on such devices. It is common belief that the complexity of the cryptographic computations are also the bottleneck of the new, quantum-resistant algorithms and that hardware accelerators are necessary to use them efficiently on energy constrained embedded devices. In this paper, we carried out an in-depth investigation of the application of potential Post-Quantum Cryptography algorithms, which were proposed in the associated US NIST process, to a representative TLS-based low-power IoT infrastructure. First, we show that the main contributor to the TLS handshake latency are the higher bandwidth requirements of post-quantum Key-Encapsulation Mechanisms rather than the cryptographic computations itself. Second, from the perspective of crypto-agility we show that edge devices with code-based, isogeny-based as well as lattice-based algorithms have low energy consumption, which enables long battery run times in typical IoT scenarios without dedicated hardware accelerators. Third, we increase the level of security further by combining pre-quantum and post-quantum algorithms to a hybrid key exchange, and quantify the overhead in energy consumption and latency of it.","PeriodicalId":130134,"journal":{"name":"Proceedings of the International Conference on Internet-of-Things Design and Implementation","volume":"271 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134038249","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}

Based on a communication schedule, TSCH exploits time-synchronization combined with frequency channel hopping to cope with wireless interference and multi-path fading. While standards define mechanisms for the basic configuration and communication of TSCH nodes, computing and adapting a schedule to the network and traffic dynamics are left as open research problems. In this paper, we propose a novel Distributed Traffic-aware Scheduling Function (DT-SF) for mobile IoT networks. DT-SF dynamically adapts the TSCH schedule to the changes of the traffic and the network topology. It estimates the node mobility by using a new lightweight approach and monitors the queue backlog to balance the traffic loads of children nodes. We model allocating TSCH timeslots to one-hop neighbors as a Mixed-Integer Convex Programming (MICP) problem which is solved by using the method of Lagrange multipliers and the Branch-and-Bound algorithm. We implement DT-SF on Zolerita Firefly IoT motes and the Contiki operating system to evaluate its performance on the testbed with 18 nodes. Evaluation results show that DT-SF improves the packet delivery ratio by up to 52% compared to the state-of-the-art method.","PeriodicalId":130134,"journal":{"name":"Proceedings of the International Conference on Internet-of-Things Design and Implementation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129952777","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}

These systems serve as hubs for other IoT devices and deliver content from streaming media services. However, such an arrangement creates a number of security concerns. For instance, providing such devices with long-term secrets is problematic with regards to vulnerable devices and fails to capture the increasingly transient nature of the relationship between users and the devices (e.g., in hotel or airbnb settings, this device is not owned by the customer and may only be used for a single day). Moreover, the limited interfaces available to such speakers make entering such credentials in a safe manner difficult. We address these problems with Lux, a system to provide ephemeral, fine-grained authorization to smart speakers which can be automatically revoked when the user and hub are no longer in the same location. We develop protocols using the LED/light channel available to many smart speaker devices to help users properly identify the device with which they are communicating, and demonstrate through a formally validated protocol that such authorization takes only a few seconds in practice. Through this effort, we demonstrate that Lux can safely authorize devices to access user accounts while limiting any long-term exposure to compromise.","PeriodicalId":130134,"journal":{"name":"Proceedings of the International Conference on Internet-of-Things Design and Implementation","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131786780","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}
