Safety is a topic that is frequently discussed and spoken of in today’s society. An enhanced security for each individual is something many strive for in various industries. One of these is how to make the public feel more secure when the person in question, for example, is out walking late at night. The goal of this bachelors thesis is thus to describe and explain the product that has been developed to get ordinary people to feel more secure wherever they are. The chosen solution for this issue was hence to develop the product SmartBand Alert which consists of two parts. A bracelet and an application for IOS and Android. This bracelet should, by certain connectivity cooperate with the user’s phone to notify family members and/or others when the person thinks or knows that he or she is in danger. These persons will be notified with information about the person who has activated the alarm to simply and easily take the necessary actions to help the person. The product is designed to be used by anyone regardless of gender, age, and other characteristics individuals may hold.

The purpose of this project was to investigate if it is possible to have local wireless control of an industrial robot. This was achieved by first doing a diversity of research. Based on the research, the project was conceptualized and a real-life product was developed showcasing the functionality. The standard robot set up as of today consists of three main parts: A robot, a control unit and a handheld controller device, called Teach Pendant. All of these parts are connected with long aggravating cables. The cables cause inconvenience and can in some cases introduce unnecessary risks in the factory. Can this hardware be removed, and an overall more convenient use case be developed? The product was developed by programming an application on a Windows tablet. Further, a Bluetooth Low Energy server was created to handle the communication between the tablet and the robot control unit. The final product consisted of a tablet, a single-board computer, a robot and a control unit. The tablet is what replaces the Teach Pendant as a handheld device. The tablet is connected to the singleboard computer via Bluetooth. The single-board computer acts as a Bluetooth server and sends out advertisements for the tablet to detect. When the tablet detects a nearby robot it can then connect to it and send start and stop commands. The server then forwards it to the control unit which finally sends the data to the robot control unit to execute. The project shows that it is possible to develop wireless robot control. It showcases a potential solution on how one could set it up. However, the final product developed had a simple functionality compared to the wired Teach Pendant. To manage the same capacity as the wired Teach Pendent, further development is required.

The Internet of Things (IoT) has seen exceptional adoption in recent years, resulting in an unprecedented level of connectivity in personal and industrial domains. In parallel, software-defined radio (SDR) technology has become increasingly powerful, making it a compelling tool for wireless security research across multiple communication protocols. Specifically, SDRs are capable of manipulating the physical layer of protocols in software, which would otherwise be implemented statically in hardware. This flexibility enables research that goes beyond the boundaries of protocol specifications. This dissertation pursues four research directions that are either enabled by software-defined radio technology, or advance its utility for security research. First, we investigate the anti-tracking mechanisms defined by the Bluetooth Low Energy (BLE) wireless protocol. This protocol, present in virtually all wearable smart devices, implements address randomization in order to prevent unwanted tracking of its users. By analyzing raw advertising data from BLE devices using SDRs, we identify a vulnerability that allows an attacker to track a BLE device beyond the address randomization defined by the protocol. Second, we implement a compact, SDR-based testbed for physical layer benchmarking of wireless devices. The testbed is capable of emulating multiple data transmissions and produce intentional signal corruption in very precisely defined ways in order to investigate receiver robustness and undefined device behavior in the presence of malformed packets. We subject a range of Wi-Fi and Zigbee devices to specifically crafted packet collisions and "truncated packets" as a way to fingerprinting wireless device chipsets. Third, we introduce a middleware framework, coined "Snout", to improves accessibility and usability of SDRs. The architecture provides standardized data pipelines as well as an abstraction layer to GNU Radio flowgraphs which power SDR signal processing. This abstraction layer improves usability and maintainability by providing a declarative experiment configuration format instead of requiring constant manipulation of the signal processing code during experimentation. We show that Snout does not result in significant computational overhead, and maintains a predictable and modest memory footprint. Finally, we address the visibility problem arising from the growing number of IoT protocols across large bands of radio spectrum. We model an SDR-based IoT monitor which is capable of scanning multiple channels (including across multiple protocols), and employs channel switching policies to maximize freshness of information obtained by transmitting devices. We present multiple policies and compare their performance against an optimal Markov Decision Process (MDP) model, as well as through event-based simulation using real-world device traffic. The results of this work demonstrate the use of SDR technology in privacy and security research of IoT device communication, and open up opportunities for further low-layer protocol discoveries that require the use of software-defined radio as a research tool.

This is our thesis for the course Degree Project in Electronics and Computer Engineering (IL122X). Our project was carried out at the company Westermo which is working on making industry network equipment. Westermo wanted a method for sending information from one of their network devices to a mobile device using secure wireless communication. It was first planned to be done using Bluetooth, and exchange keys through NFC. This was later changed to not just evaluate this particular situation, but to evaluate the best solution for their use-case. This report will go through our evaluation process. We will mention different possible techniques and if they can be used, then put the techniques together and form a possible solution. Our discussion will mention what we think is the best solution and why, and the way forward.

Industrial Development Centre (IUC) in Olofström inc. has constructed a measurement value logger which can sample values from eight channels, buffer them and then send them wireless with the Bluetooth technology to e.g. a computer.</p> In this thesis the data transfer rate, i.e. the number of values per second has been studied for different logger settings and when there are interferences in the Bluetooth traffic. How Bluetooth is affected by interferences has been studied with a number of experiments performed at IUC's RF-damped Faraday's cage. The thesis provides a model for this Bluetooth logger. The model extends the existing simulation system NS2-UCBT with a 'logger protocol'. NS2-UCBT was also extended to better support modeling of losses (due to Bluetooth channel impairments) and for the model of these losses to be based on experiments. The resulting simulation program allows developers to construct and evaluate a measurement system utilizing such a Bluetooth logger. Using the simulation model, the data rate measured in samples per second was examined for the logger. The simulations shows that optimizing the logger's configuration will improve that data rate considerable. This report contains: a summary of the problem and earlier research, an explanation of the simulation system and the simulation program, comparisons between simulations and experiments, some conclusions, and proposes future work in this area. / Industriellt Utvecklings Centrum (IUC) i Olofström AB har tagit fram en mätvärdeslogger som kan sampla värden från åtta kanaler, mellanlagra dem och skicka dem till exv. en dator trådlöst med Bluetooth teknologin. I det här examensarbetet har överföringshastigheten, dvs antal mätvärden per sekund studerats för olika inställningar på loggern och då det förekommer störningar i Bluetooth trafiken. Hur Bluetooth påverkas av störningar har undersökts genom en rad experiment i IUC's RF-dämpade skärmlabb. Arbetet har lett fram till en modell för mätvärdesloggern och ett simuleringsprogram som gör det möjligt för utvecklare att konstruera och utvärdera sina mätsystem med mätvärdes logger. Modellen använder det befintliga NS2-UCBT simuleringssystemet utvidgat med ett 'logger protokoll', mer utvecklad förlusthantering än NS2-UCBT i grundutförandet erbjuder och flexibel förlusthantering baserad på experiment. Med simuleringsmodellen undersöktes loggerns datahastighet i sampel per sekund. Simuleringarna visa att genom att förbättra loggerns konfiguration kan avsevärt högre datahastighet nås. Den här rapporten innehåller: en sammanfattning av problemställningen och tidigare forskning, en beskrivning av simulationssystemet och simulationsprogrammet, jämförelser mellan simuleringar och experiment, en del slutsatser, och förslag på framtida arbete i området.
