    Sammanfattning : In recent years, quantum computers have achieved new levels of sophistication and are by some estimates only a few years from being used in production. A growing body of literature points toward their potential uses within various industries, with the finance industry identified as exceptionally full of prospective applications. LÄS MER

  4. 3. Authentication in quantum key growing

    Uppsats för yrkesexamina på grundnivå, Matematiska institutionen

    Författare :Jörgen Cederlöf; [2005]
    Nyckelord :Quantum key growing; Quantum key generation; Quantum key distribution; Quantum cryptography; Message authentication; Unconditional security; Rényi entropy.;

    Sammanfattning : Quantum key growing, often called quantum cryptography or quantum key distribution, is a method using some properties of quantum mechanics to create a secret shared cryptography key even if an eavesdropper has access to unlimited computational power. A vital but often neglected part of the method is unconditionally secure message authentication. LÄS MER
