  1. 6. Contributions to unconditionally secure authentication

    Författare :Thomas Johansson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis concerns unconditionally secure authentication, i.e., providing protection against an enemy who is assumed to have unlimited computing power. The field is divided into two areas, conventional authentication and authentication for non-trusting parties. LÄS MER

  3. 7. 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

  4. 8. Lightweight Authentication in Wireless Networks

    Författare :Henric Johnson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis, we develop and analyse two novel authentication protocols well suited for wireless devices. iven that wireless devices have limited resources such as processing power, bandwidth, storage, and energy, the proposed authentication protocols need to be lightweight.

  5. 9. On Some Symmetric Lightweight Cryptographic Designs

    Författare :Martin Ågren; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight cryptography; integrity; authentication; symmetric cryptography; stream ciphers; block ciphers; Grain-128a; BEAN; KTANTAN; textsc{PRINTcipher}; FCSR combiner; related-key attack; linear cryptanalysis; linear correlations; invariant subspace attack.;

    Sammanfattning : This dissertation presents cryptanalysis of several symmetric lightweight primitives, both stream ciphers and block ciphers. Further, some aspects of authentication in combination with a keystream generator is investigated, and a new member of the Grain family of stream ciphers, Grain-128a, with built-in support for authentication is presented.
