  1. 11. Aggregating Certificate Transparency Gossip Using Programmable Packet Processors

    Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :Rasmus Dahlberg; [2018]
    Nyckelord :Certificate Transparency; CT; Gossip; P4;

    Sammanfattning : Certificate Transparency (CT) logs are append-only tamper-evident data structures that can be verified by anyone. For example, it is possible to challenge a log to prove certificate inclusion (membership) and log consistency (append-only, no tampering) based on partial information. LÄS MER

  3. 12. Assessing blockchain technology for Transport Data Logger

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

    Författare :Björn Johansson; [2018]
    Nyckelord :blockchain; transport data logger; hyperledger; hyperledger fabric; byzantine fault tolerance; bft; supply chain; transport chain; permissioned; permissionless; documental truth; historical truth; immutability; security; log data; Technology and Engineering;

    Sammanfattning : A proof of concept permissioned blockchain system that holds data from the Transport Data Logger, TDL, was developed. Transport chain actors who hand off TDL-equipped goods between one another use the TDL app to upload a digital handoff containing their identities and log data from and signed by the TDL to a Hyperledger Fabric blockchain network.

  4. 13. Tampering Classification Using Accelerometer Data

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Mikael Lindholm; Linus Lindgren; [2017]
    Nyckelord :machine learning; classification; accelerometer; support vector machine; doorstation; tampering detection; Mathematics and Statistics;

    Sammanfattning : Network Video Door Stations are IP-based door stations for two-way communication, identification, and remote entry control. They have a number of different sensors e.g video, audio and accelerometer that can measure external data. LÄS MER

  5. 14. Privacy Preserving Audit Proofs

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Anton Lindqvist; [2017]
    Nyckelord :privacy; audit; logging; security; bloom filter; merkle tree;

    Sammanfattning : The increased dependence on computers for critical tasks demands sufficient and transparent methods to audit its execution. This is commonly solved using logging where the log must not only be resilient against tampering and rewrites in hindsight but also be able to answer queries concerning (non)-membership of events in the log while preserving privacy.

  7. 15. Digital Forensics applications towards digitized collections in Cloud : a process approach to gathering evidences for authenticity, integrity and accessibility

    Master-uppsats, Luleå tekniska universitet/Datavetenskap

    Författare :Sanjay Singh; [2017]
    Nyckelord :Cloud; Archiving; Forensics; Preservation;

    Sammanfattning : The growth of data/information on social media and in large organizations is huge in terms of velocity, volume and variety which is also something being tackled by the large IT companies providing Big Data solutions. The other challenges which are linked to managing the huge pile of data are about ensuring preservation and access of crucial data which has implications in every sector ranging from pharmaceuticals to aerospace and cultural institutions (museums, archives and governmental records).
