  1. 1. Distributed Relay/Replay Attacks on GNSS Signals

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Malte Lenhart; [2022]
    Keywords : Global Navigation Satellite System GNSS ; Spoofing; Relay Replay Attack; Software Defined Radio SDR ; Security; Satellitnavigeringssystem; Spoofing; Relay Replay Attack; Software Defined Radio SDR ; Säkerhet;

    Abstract : In modern society, Global Navigation Satellite Systems (GNSSs) are ubiquitously relied upon by many systems, among others in critical infrastructure, for navigation and time synchronization. To overcome the prevailing vulnerable state of civilian GNSSs, many detection schemes for different attack types (i.e. READ MORE

  3. 2. Digital Microwave Control of Superconducting Qubits

    University essay from KTH/Tillämpad fysik

    Author : Giuseppe Ruggero Di Carlo; [2022]
    Keywords : Superconducting qubit; High-fidelity readout; Real-time reset; iSwap gate; FPGA; RFSoC; template matching.; Supraledande kvantbit; Avläsning med hög tillförlitlighet; realtidsåterställning; iSwap-grind; FPGA; RFSoC; mallmatchning.;

    Abstract : We manipulate two superconducting qubits using digital microwave electronics. Starting fromtheir characterization, we develop a real-time reset scheme and implement the iSwap gate. Thequbits’ parameters are obtained using standard single-qubit characterization techniques, such asRabi and Ramsey oscillations and frequency sweep of the resonators. READ MORE

  4. 3. Bluetooth low energy mesh logger

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Oskar Olsson; Ossian Sandell; [2022]
    Keywords : IoT; Bluetooth Low Energy; Mesh; synchronization; nRF; Zephyr; SoC; 9-DoF sensor; Technology and Engineering;

    Abstract : This thesis aims to make a prototype that does sampling from gyroscopes, accelerometers and compasses with as little as one millisecond difference between every unit that samples. Longer term tests to gather data of the characteristics of the Bluetooth low energy mesh were made. READ MORE

  5. 4. Model-based Generation of a Sensor Reading Web Test Tool

    University essay from Lunds universitet/Institutionen för datavetenskap

    Author : Jonas Andersson; Christoffer Lindell Bolin; [2022]
    Keywords : WISE; GUI; REST; Testing; Integration; Technology and Engineering;

    Abstract : This Bachelor’s thesis is in collaboration with Saab Kockums AB. Saab Kockums develops and constructs marine technology, ships and submarines for civil and military use. READ MORE

  6. 5. Fast Clock Synchronization for Large-Scale MEMS Ultrasonic Transducer Arrays

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Karl-Johan Karlsson; [2022]
    Keywords : clock synchronization; clock deskew; MEMS transducer; Delay line; Time-to-Digital conveter;

    Abstract : In many systems today sensors or transmitters need to be read or controlled simultaneously. This thesis investigates a new architecture used for deskewing clock signals between multiple separated parts of a signal transmission system. READ MORE
