    Sammanfattning : Internet of Things, or the infrastructure of the information age society, is an expanding area of research. It is the idea that physical things that we have today, can be turned into devices by being connected to a network. LÄS MER

  3. 17. End-to-end Security Enhancement of an IoT Platform Using Object Security

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Hampus Tjäder; [2017]
    Nyckelord :Object security; COSE; IoT security; End-to-end security; CoAP; LWM2M; Bluetooth Low Energy; BLE security;

    Sammanfattning : The Internet of Things (IoT) is seen as one of the next Internet revolutions. In a near future the majority of all connected devices to the Internet will be IoT devices. These devices will connect previously offline constrained systems, thus it is essential to ensure end-to-end security for such devices. LÄS MER

  4. 18. Publish-Subscribe Communication for CoAP

    Kandidat-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Jussi Haikara; [2017]
    Nyckelord :;

    Sammanfattning : Low powered Internet of Things solutions such as wireless sensor networks often operate under heavy constraints, and require special care in the design of their communication models. This project consists of implementing and evaluating the proposed IETF draft of the publish-subscribe communication model for the Constrained Application Protocol (CoAP) on a wireless sensor network (WSN) using the Contiki operating system.

  5. 19. Designing Applications for use of NB-IoT

    Kandidat-uppsats, Malmö högskola/Fakulteten för teknik och samhälle (TS)

    Författare :John Tengvall; Dennis Wildmark; [2017]
    Nyckelord :LPWAN; Narrowband IoT; NB-IoT; Application Design; Software Development; HTTP; CoAP; Comparison;

    Sammanfattning : IoT är en marknad som har växt fort under de senaste åren och skapat sig en egen industri. Kärnan i IoT är internetanslutningen och i många fall är mobil kommunikation den bästa lösningen för en IoT-produkt. Problemet är att det inte finns något självklart val av mobil kommunikation för användning i en IoT-produkt. LÄS MER

  7. 20. Efficient Group Key Management for Internet of Things

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)
