    Sammanfattning : Cryptography is the science and art of keeping information secret to un-intended parties. But, how can we determine who is an intended party and who is not? Authentication is the branch of cryptography that aims at confirming the source of data or at proving the identity of a person. This Ph.D. LÄS MER

  4. 3. Authentication in Quantum Key Distribution : Security Proof and Universal Hash Functions

    Författare :Aysajan Abidin; Jan-Åke Larsson; Viiveke Fåk; Robert Forchheimer; Joseph Merrill Renes; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Quantum Key Distribution (QKD) is a secret key agreement technique that consists of two parts: quantum transmission and measurement on a quantum channel, and classical post-processing on a public communication channel. It enjoys provable unconditional security provided that the public communication channel is immutable. LÄS MER
