  1. 6. Hardened Model Aggregation for Federated Learning backed by Distributed Trust Towards decentralizing Federated Learning using a Blockchain

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Morsbach Felix Johannes; [2020]
    Nyckelord :;

    Sammanfattning : Federated learning enables the training of machine learning models on isolated data islands but also introduces new security challenges. Besides training-data-poisoning and model-update-poisoning, centralized federated learning systems are subject to a third type of poisoning attack: model-aggregation-poisoning. LÄS MER

  3. 7. Performance Evaluation of a Blockchain-based Traceability System : A Case Study at IKEA

    Master-uppsats, Linköpings universitet/Programvara och system

    Författare :Tobias Sund; Claes Lööf; [2019]
    Nyckelord :blockchain; traceability; supply chain;

    Sammanfattning : Establishing traceability in global supply chains is a complicated problem. Current solutions for achieving traceability are expensive or imperfect, and give rise to organizational and trust-related issues. Blockchain could present itself as a solution to many of these issues. This thesis aims to build a blockchain-based traceability system. LÄS MER

  4. 8. Transparency analysis of Distributed file systems : With a focus on InterPlanetary File System

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

    Författare :Oscar Wennergren; Mattias Vidhall; Jimmy Sörensen; [2018]
    Nyckelord :Distributed file systems; replication; performance; scalability; security; transparency;

    Sammanfattning : IPFS claims to be the replacement of HTTP and aims to be used globally. However, our study shows that in terms of scalability, performance and security, IPFS is inadequate. This is a result from our experimental and qualitative study of transparency of IPFS version 0.4. LÄS MER
