  1. 1. Blockchain-based e-voting system without digital ID: A Proof-of-Concept

    Kandidat-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :Leonard Schick; [2024]
    Nyckelord :Computer science; Cryptography; Crypto; Blockchain; Distributed systems; e-voting; electronic voting; Ethereum; Hyperledger; Hyperledger besu; Decentralization; Datavetenskap; Kryptografi; Blockkedja; Distribuerade system; e-röstning; Elektronisk röstning; Blinda signaturer; Ethereum; Hyperledger Besu; Decentralisering;

    Sammanfattning : Electronic voting systems have the potential to offer a cost effective, secure and transparent way of communicating with the citizens, increasing trust and participation. However creating a secure open source electronic voting system providing confidentiality and transparency with sufficient performance has long been a challenge. LÄS MER

  3. 2. Choosing authentication protocol for digital signatures : A comparison between SAML and OIDC

    M1-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Pontus Kågström; [2023]
    Nyckelord :OpenID Connect SAML OIDC Security Assertion markup language;

    Sammanfattning : More and more companies are working toward digitizing their workflow and this has increased the necessity of digital signatures.An important part of digital signatures is the authentication process which is heavily regulated for Swedish government agencies by DIGG, DIGG only allows the use of Security Assertion Mark-up Language(SAML) for authentication but are looking into also allowing OpenID Connect(OIDC) and together with Swedish OIDC working group produce a specification.

  4. 3. Remote Sensing of Cryospheric Surfaces : Small Scale Surface Roughness Signatures in Satellite Altimetry Data

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Petter Ideström; [2023]
    Nyckelord :Remote sensing; Altimetry; Arctic; Cryosphere; ICESat-2; Cryosat-2; Svalbard;

    Sammanfattning : The Arctic cryosphere is experiencing a higher rate of warming compared to the rest of the world due to Arctic amplification. As glacier elevation change provide reliable evidence of climate change it is routinely measured by satellite altimeters. LÄS MER

  5. 4. GitBark : A Rule-Based Framework for Maintaining Integrity in Source Code Repositories

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

    Författare :Elias Bonnici; [2023]
    Nyckelord :Source Code Integrity; Version Control System; Git; Threat modeling; Digital signatures; Källkodsintegritet; Versionshanteringssystem; Git; Hotmodellering; Digitala signaturer;

    Sammanfattning : In today’s digital landscape, maintaining the integrity of source code is crucial for delivering reliable and trustworthy software solutions. However, the increasing prevalence of attacks targeting source code repositories and version control systems (VCSs) poses significant challenges to source code integrity. LÄS MER

  7. 5. Evaluating the performance of FPGA-based Secure Hash Algorithms for use in SPHINCS+

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

    Författare :Kei Duke-Bergman; Alexander Huynh; [2023]
    Nyckelord :Bachelor’s thesis; FPGA; SHA; Cryptography; Kandidatexamensarbete; FPGA; SHA; Kryptografi;

    Sammanfattning : In the digital landscape of today, large amounts of transactions, messaging and different kinds of authorizations are carried out online. To ensure the the integrity and security of these systems, digital signature systems are used to verify the identity of different individuals and entities. LÄS MER
