  1. 1. Investigating programming language support for fault-tolerance

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

    Författare :Ismail Demirkoparan; [2023]
    Nyckelord :Dataflow; Fault tolerance; Data streaming; Distributed systems; Checkpointing; Logging; Lineage; Lineage stash; Arc-Lang; Apache Flink;

    Sammanfattning : Dataflow systems have become the norm for developing data-intensive computing applications. These systems provide transparent scalability and fault tolerance. For fault tolerance, many dataflow-system adopt a snapshotting approach which persists the state of an operator once it has received a snapshot marker on all its input channels. LÄS MER

  3. 2. Improving Availability of Stateful Serverless Functions in Apache Flink

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

    Sammanfattning : Serverless computing and Function-as-a-Service are rising in popularity due to their ease of use, provided scalability and cost-efficient billing model. One such platform is Apache Flink Stateful Functions. LÄS MER

  4. 3. Battery-less IoT Devices: Energy Source Manipulation Attacks

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Arslan Hameed; [2022]
    Nyckelord :;

    Sammanfattning : The Internet of Things (IoT) is expected to enable applications of utmost societal value, such as energy-efficient buildings, smart cities, and next-generation healthcare. While there has been a lot of progress on the security of larger devices, there is a need to consider the security of resource-constrained devices. LÄS MER

  5. 4. A Comparative Study Of Proof of Stake Algorithms

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

    Författare :Antonio Saaranen; [2022]
    Nyckelord :Blockchain; consensus algorithms; cryptography; Proof of Stake; Technology and Engineering;

    Sammanfattning : Cryptocurrencies are growing at a rapid pace. It is well established that the mining operation fueling the cryptocurrency Bitcoin consumes a significant amount of energy. This study aims to determine if there is an alternative to the consensus model, maintaining security, integrity, and decentralization. LÄS MER

  7. 5. Secure Intermittent Computing

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

    Författare :Erik Henricus Wouters; [2019]
    Nyckelord :;

    Sammanfattning : Low-power embedded systems exist in many forms. Using batteries for these devices generally imposes high maintenance costs and there are many applications where a grid connection is not feasible [1]. A solution for powering this class of embedded systems is energy harvesting. LÄS MER
