  1. 1. PUF-enabled blockchain for IoT security : A comparative study

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Jonathon Bisiach; Victor Elfving; [2021]
    Nyckelord :Internet of Things; Internet of Everything; Blockchain; Physical Unclonable Functions; Consensus Algorithms; Proof of Work; Proof of Authentication; Proof of PUF-enabled Authentication;

    Sammanfattning : The introduction of Physical Unclonable Functions (PUFs) and lightweight consensus algorithms to aid in the bolstering of security and privacy in both IoT and IoE does show a great deal of promise not only in these areas, but in resource cost over traditional methods of blockchain.  However, several previous studies make claims regarding performance of novel solutions without providing detailed information as to the physical components of their experiments.

  3. 2. An FPGA Implementation of Arbiter PUF with 4x4 Switch Blocks

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

    Författare :Can Aknesil; [2020]
    Nyckelord :;

    Sammanfattning : Theft of services, private information, and intellectual property have become significant dangers to the general public and industry. Cryptographic algorithms are used for protection against these dangers. All cryptographic algorithms rely on secret keys that should be generated by an unpredictable process and securely stored.

  4. 3. Lightweight and Machine Learning Attack Resistant Physical Unclonable Functions

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

    Författare :Oskar Näslund; [2019]
    Nyckelord :;

    Sammanfattning : More and more embedded devices such as smart home appliances are being connected to the Internet. Implementing lightweight security at a low cost thus becomes increasingly relevant to prevent malicious network entries using less protected devices. LÄS MER

  5. 4. Characterization of FPGA-based Arbiter Physical Unclonable Functions

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

    Författare :Jingnan Shao; [2019]
    Nyckelord :Arbiter PUF; FPGA; Altera; Verilog HDL; Arbiter PUF; FPGA; Altera; Verilog HDL;

    Sammanfattning : The security of service, confidential data, and intellectual property are threatened by physical attacks, which usually include reading and tampering the data. In many cases, attackers can have access to the tools and equipment that can be used to read the memory or corrupt it, either by invasive or non-invasive means. LÄS MER

  7. 5. Physical Proximity Verification based on Physical Unclonable Functions

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

    Författare :Marco Spanghero; [2018]
    Nyckelord :;

    Sammanfattning : There are rapidly growing concerns about security of hardware implementing cryptographic algorithms. A compromised device can potentially be used as an entry point for cyberattacks on other devices connected to the network, as evidenced by the recent Spectre and Meltdown CPU bugs. LÄS MER
