  1. 1. Homomorphic encryption

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Daniel Sanaee; [2023]
    Nyckelord :Mathematics; Cryptography; Computer science; Group Theory; Matematik; Kryptografi; Datalogi; Gruppteori;

    Sammanfattning : The problem of constructing a secure encryption scheme that allows for computation on encrypted data was an open problem for more than 30 years. In 2009, Craig Gentry solved the problem, constructing the first fully homomorphic encryption (FHE) scheme. LÄS MER

  3. 2. An Introduction to Symmetry Protected Topological Phases

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :David Petrovic; [2023]
    Nyckelord :;

    Sammanfattning : In this thesis, we aim to display characteristics of symmetry protected topological phases within quantum mechanics (QM). Building on well known aspects of QM, we relate the formalism to basic group representation theory, and review the connection between projective symmetries and protected vacuum degeneracies. LÄS MER

    Sammanfattning : hälsotillstånd. Individer med intellektuell funktionsnedsättning, autism, eller båda nedsättningar, har ofta högre risk att hamna i social isolering än individer utan dessa funktionsnedsättningar. LÄS MER

  5. 4. Dielectric properties of ion-exchanged electrotechnical insulation papers : A study on the properties of novel papers

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

    Författare :Dan Selsmark; [2023]
