    Sammanfattning : Internet of Things (IoT) devices are devices with embedded sensors or software. Their usage is becoming more prevalent. They are used for smart homes, traffic tracking, weather data and sensor networks. Often IoT devices communicate wirelessly using low-power protocols. LÄS MER

  3. 7. Analysis of DTLS Implementations Using State Fuzzing

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Fredrik Tåkvist; [2020]
    Nyckelord :;

    Sammanfattning : Despite being unreliable, UDP is the prefered choice for a growing number ofimplementations due to its low latency. Hence, a means for protecting sensitive datasent over UDP is essential. The protocol most commonly used for this purpose is Datagram Transport Layer Security (DTLS). LÄS MER

  4. 8. Building Datagram Transport Layer Security (DTLS)-based access control in the Internet-of-Things

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Chenxi Feng; [2020]
    Nyckelord :;

    Sammanfattning : With the widespread use of the Internet of Things (IoT), the security problem has raised social attention. Due to the limited calculation ability of the constrained device, it is difficult to download the defense software inside and the device just can use the built-in encryption mechanisms to defend attack.

  5. 9. An Internet of Things Software and Firmware Update Architecture Based on the SUIT Specification

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Simon Carlson; [2019]
    Nyckelord :IoT; industrial IoT; security; Contiki-NG; embedded systems; software updates; IoT; industriell IoT; säkerhet; Contiki-NG; inbyggda system; mjukvaruuppdateringar;

    Sammanfattning : As society becomes more digitalized, cyberattacks are increasingly common and severe. Security in the Internet of Things (IoT) is essential, and IoT devices must be updated to patch vulnerabilities. LÄS MER

  7. 10. Energy-Efficient Communication with Lightweight M2M in IoT Networks

    Uppsats för yrkesexamina på avancerad nivå, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Carlos Gonzalo Peces; [2018]
    Nyckelord :IoT; LwM2M; low power consumption; TSCH; Contiki-NG; Eclipse Leshan.; IoT; LwM2M; låg energiförbrukning; TSCH; Contiki-NG; Eclipse Leshan.;

    Sammanfattning : OMA’s Lightweight Machine to Machine (LwM2M) is an application protocol for device management in the Internet of Things (IoT) that has been recently published and widely adopted in a lot of projects. The protocol is designed to operate in sensor networks and machine-to-machine environments, where one of the main constraints is the energy consumption since the nodes are usually battery powered.
