  4. 23. Security in low power wireless networks : Evaluating and mitigating routing attacks in a reactive, on demand ad-hoc routing protocol

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Tony Fredriksson; Niklas Ljungberg; [2017]
    Nyckelord :IoT; Security; Ad-hoc Routing; RIME; Sinkhole; Selective Forwarding; Sybil; Intrusion Detection System;

    Sammanfattning : Using low energy devices to communicate over the air presents many challenges to reach security as resources in the world of Internet Of Things (IoT) are limited. Any extra overhead of computing or radio transmissions that extra security might add affects cost of both increased computing time and energy consumption which are all scarce resources in IoT.

  5. 24. The implementation of peer-to-peer in flash crowds: A case study of bandwidth and cost reduction for over-the-air updates

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Artur Matulaniec; [2017]
    Nyckelord :peer-to-peer; over-the-air; OTA; p2p; hole punching; NAT; IPv4; IPv6; economic gain; Technology and Engineering;

    Sammanfattning : This thesis will examine the plausibility of exchanging protocol from a normal server-client to a peer-to-peer solution for over-the-air updates, using a single case study for Sony Mobile Communications AB in Lund, Sweden. It will examine the effort, the risks, and what the actual gain may be comparing to a client-server approach for over-the-air software updates. LÄS MER

    Nyckelord :;

    Sammanfattning : In cellular networks, the roaming interconnection was designed when there were only a few trusted parties and security was not a major concern or design criteria. Most of the roaming interconnections today are still based on the decades-old SS7 and the lack of security is being blamed for several vulnerabilities. LÄS MER
