  1. 1. Generation and detection of entangled single-photon pairs

    Kandidat-uppsats, Uppsala universitet/FREIA

    Författare :Gabriella Tesfamichael Habtezion; [2024]
    Nyckelord :;

    Sammanfattning : Quantum information technology is an emerging field with important applications such as quantum cryptography and teleportation, quantum imaging and lithography. These applications make use of single photons and pairs of entangled photons. In this work, we experimentally generate and attempt to detect the entangled photons. LÄS MER

  3. 2. The Effect of Noise Levels on the Performance of Shor’s Algorithm

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

    Författare :Niklas Höstedt; Tobias Ljunggren; [2023]
    Nyckelord :Bachelor’s thesis; Quantum Computing; Shor’s algorithm; Noise; Cryptography; Qiskit; Kandidatexamensarbete; Kvantdatorer; Shors algorithm; Brus; Kryptografi; Qiskit;

    Sammanfattning : Advanced enough quantum computers promise to revolutionise fields such as cryptography, drug discovery and simulations of complex systems. Quantum computers are built on qubits which are fragile and susceptible to error-inducing interference, which is called noise. LÄS MER

  4. 3. A Side-Channel Attack on Masked and Shuffled Implementations of M-LWE and M-LWR Cryptography : A case study of Kyber and Saber

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

    Författare :Linus Backlund; [2023]
    Nyckelord :Public-key Cryptography; Post-Quantum Cryptography; Kyber; Saber; Side-Channel Attack; Power Analysis; Asymetrisk Kryptering; Kvantsäker Kryptografi; Kyber; Saber; Sidokanalsattack; Effektanalys;

    Sammanfattning : In response to the threat of a future, large-scale, quantum computer, the American National Institute of Standards and Technology (NIST) initiated a competition for designs of quantum-resistant cryptographic primitives. In 2022, the lattice-based Module-Learning With Errors (M-LWE) scheme Kyber emerged as the winner to be standardized. LÄS MER

  5. 4. 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

  7. 5. Experimental Evaluation of Kleptographic Backdoors in LWE-based KEMs

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Miriam Rosén; [2023]
    Nyckelord :cryptography; post-quantum; backdoor; kleptography;

    Sammanfattning : This work aims to provide an experimental evaluation of two kleptographic backdoors. The backdoors target the key generation step in Learning with Errors-based crypto algorithms and exploit freedom in choosing the seeds for the algorithm. LÄS MER
