  4. 3. Authentication in quantum key growing

    University essay from Matematiska institutionen

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

    Abstract : 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. READ MORE
