Cyber security plays a key role in embedded systems, especially for the domain of the Internet of Things (IoT). IoT systems of this kind are becoming increasingly important in daily life as they simplify various tasks. They are usually small, either embedded into bigger systems or battery driven, and perform monitoring or one shot tasks. Thus, they are subject to manifold constraints in terms of performance, power consumption, chip area, etc. As they are continuously connected to the internet and utilize our private data to perform their tasks, they are interesting for potential attackers. Cyber security thus plays an important role for the design of an IoT system. As the usage of security measures usually increases both computation time, as well as power consumption, a conflict between these constraints must be solved. For the designers of such systems, balancing these constraints constitutes a highly complex task. In this paper we propose a novel approach for considering possible security attacks on embedded systems, simplifying the consideration of security requirements immediately at the start of the design process. We introduce a security aware design space exploration framework which based on an architectural, behavioral and security attack description, finds the optimal design for IoT systems. We also demonstrate the feasibility and the benefits of our framework based on a door access system use case.","PeriodicalId":217233,"journal":{"name":"2019 22nd Euromicro Conference on Digital System Design (DSD)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126175405","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}

Memory isolation mechanisms are often absent, programming flaws lead to malfunctioning applications, which in turn can crush the whole system. A common design approach in these devices is to have applications, operating system components, and device driver libraries reside in a single non-isolated address space, which represents one vast attack surface. Furthermore, with increasing network connectivity and frequent dynamic updates, new or modified applications and services are uploaded, opening space for even more attacks. Isolating the execution of applications in these systems is still a challenge. In this work we provide a holistic hardware/software co-designed approach for memoryisolation, which prevents corruption of the state of the operating system and applications from a buggy software, including device drivers, interrupt service routines, and misused system calls. We implemented low-cost architectural extensions in a RISC-V-based microcontroller which work together with kernel-based protection concepts. Our evaluation shows that applications as well as the kernel can enjoy the benefits of the proposed memory isolation with minimal impact on performance and an insignificant increase in the area of the MCU.","PeriodicalId":217233,"journal":{"name":"2019 22nd Euromicro Conference on Digital System Design (DSD)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122607190","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}

It has allowed these sensors to be integrated into portable as well as wearable systems. Such systems are usually operated in a hands-free and always-on manner where they need to function continuously in a variety of scenarios. In such situations, relying on a single sensor or a fixed sensor combination can be detrimental to both performance as well as energy requirements. Consider the case of an obstacle detection task. Here using an RGB camera helps in recognizing the obstacle type but takes much more energy than an ultrasonic sensor. Infrared cameras can perform better than RGB camera at night but consume twice the energy. Therefore, an efficient system must use a combination of sensors, with an adaptive control that ensures the use of the sensors appropriate to the context. In this adaptation, one needs to consider both performance and energy and their trade-off. In this paper, we explore the strengths of different sensors as well their trade-off for developing a deep neural network based wearable device. We choose a specific case study in the context of a mobility assistance device for the visually impaired. The device detects obstacles in the path of a visually impaired person and is required to operate both at day and night with minimal energy to increase the usage time on a single charge. The device employs multiple sensors: ultrasonic sensor, RGB Camera, and NIR Camera along with a deep neural network accelerator for speeding up computation. We show that by adaptively choosing the appropriate sensor for the context, we can achieve up to 90% reduction in energy while maintaining comparable performance to a single sensor system.","PeriodicalId":217233,"journal":{"name":"2019 22nd Euromicro Conference on Digital System Design (DSD)","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115652867","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}

A key characteristic of such tasks is the presence of modes providing different levels of application performance in terms of metrics like accuracy. The system designer has the flexibility to select an appropriate mode for executing such tasks. Secondly, the designer also has the traditional flexibility of choosing suitable components to build the execution platform. Thirdly, the system performance might vary with various external factors (known as context), and during the initial stages of system design, the designer might have the flexibility to support only a subset of the possible contexts. This three-fold flexibility in the hands of the designer has not been explored simultaneously in prior works and raises the complexity of designing embedded systems many-fold. In this paper, we address the design of such systems through a novel framework named GRanDE (Graphical Representation and Design Space Exploration). GRanDE consists of a comprehensive graphical representation to capture the three aspects of the design space discussed earlier. Further, we transform this representation into Constraint Logic Programming (CLP) constructs, which could be used to interactively explore and prune the design space. We demonstrate the applicability of the proposed framework on an embedded system named MAVI having ~1.3 million design points. The generated CLP program could prune up to 99.74% of the design space of MAVI.","PeriodicalId":217233,"journal":{"name":"2019 22nd Euromicro Conference on Digital System Design (DSD)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116994490","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}
