  1. 1. 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

  3. 2. Weaknesses of Authentication in Quantum Cryptography and Strongly Universal Hash Functions

    Författare :Aysajan Abidin; Jan-Åke Larsson; Viiveke Fåk; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : Authentication is an indispensable part of Quantum Cryptography, which is an unconditionally secure key distribution technique based on the laws of nature. Without proper authentication, Quantum Cryptography is vulnerable to “man-in-the-middle” attacks. LÄS MER

  4. 3. Towards Inter-temporal Privacy Metrics

    Författare :Stefan Berthold; Simone Fischer-Hübner; Stefan Lindskog; Viiveke Fåk; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; privacy; unlinkability; metrics; uncertainty; valuation process; domain-specific language; anonymous communication; Computer science; Datavetenskap; Datavetenskap; Computer Science;

    Sammanfattning : Informational privacy of individuals has significantly gained importance after information technology has become widely deployed. Data, once digitalised, can be copied and distributed at negligible costs. This has dramatic consequences for individuals that leave traces in form of personal data whenever they interact with information technology. LÄS MER

  5. 4. Towards Measurable and Tunable Security

    Författare :Reine Lundin; Simone Fischer-Hubner; Stefan Lindskog; Viiveke Fåk; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tunable security; security measures; metrics; entropy; guesswork; privacy; anonymity; selective encryption; Computer science; Datavetenskap; Datavetenskap; Computer Science;

    Sammanfattning : Many security services today only provides one security configuration at run-time, and cannot then utilize the trade-off between performance and security. In order to make use of this trade-off, tunable security services providing several security configurations that can be selected at run-time are needed. LÄS MER
