  1. 11. Relay Attack Resistant Passive Keyless Entry : Securing PKE Systems with Immobility Detection

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : ABEL VALKO; [2020]
    Keywords : Passive Keyless Entry; Relay Attack; Mafia Fraud; Access Control; Mechatronics; Nyckellös System; åtkomstkontroll; Relay Attack; IT-säkerhet; Mekatronik;

    Abstract : A significant security risk of modern vehicles is their vulnerability to relay attacks, due to challenge-response methods, such as those employed in Passive Keyless Entry (PKE) used by most commercial cars, being inherently exposed. This class of attacks are where communication between a vehicle and its key is relayed by an attacker over long range - thereby bypassing any encryption and unlocking the vehicle without requiring direct access to the key.

  3. 12. Design and Development of a Measurement System to Track the Motion of a Point Absorber

    University essay from

    Author : Juliana Lüer; [2020]
    Keywords : accelerometer; AHRS; battery; buoy; data transmission; GNSS; gyroscope; IMU; solar panel; wave energy;

    Abstract : Because of climate change renewable energy field is becoming more and more relevant. Renewable energy can be gained from the sun, from wind but also from ocean waves. To support the research and development in this field reliably measured wave data is collected through a measurement system that shows the exact position of a buoy. READ MORE

  4. 13. User Deployed Hot-Spots in Rurual 5G Networks

    University essay from Linköpings universitet/Programvara och system

    Author : Nasir Zaman; [2019]
    Keywords : 5G; Rural Networks; Energy Efficiency; User Deployed Hot-Spot;

    Abstract : Cellular network expansion in rural areas has been traditionally slower than in dense urban areas. Area coverage in rural areas is fundamentally limited by the deployment cost for the operator. READ MORE

  5. 14. Evaluation of Peer-to-Peer LoRa for Geolocation Usage in a Rural Environment

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

  6. 15. IoT Framework for Water Monitoring Using the M-Bus Interface

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

    Author : Albert Asratyan; Mandar Joshi; [2019]
    Keywords : Smart water monitoring; Contiki-OS; Internet of Things IoT ; M-Bus; MQTT; 6LoWPAN; Smart vattenmätning; Contiki-OS; Sakernas Internet IoT ; M-Bus; MQTT; 6LoWPAN;

    Abstract : Immense amounts of water are wasted daily, and it is as important as ever to optimize our water consumption, especially considering that today around 850 million people lack access to clean water. With the rise of the Internet of Things, creating a monitoring system for this purpose becomes easier, but there arises a problem of interfacing water meters to IoT capable devices. READ MORE
