    Sammanfattning : Stream ciphers are cryptographic primitives that are used to ensure the privacy of a message that is sent over a digital communication channel. In this thesis we will present new cryptanalytic results for several stream ciphers. LÄS MER

  3. 2. Some results on fast correlation attacks

    Författare :Fredrik Jönsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; stream ciphers; linear feedback shift registers; cryptology; correlation attacks; cryptanalysis; Teknik; Informatics; systems theory; Informatik; systemteori;

    Sammanfattning : This thesis presents new results on fast correlation attacks on stream ciphers. In particular, fast correlation attacks on stream ciphers containing linear shift registers with an arbitrary number of taps, are considered. A general introduction to stream ciphers and correlation attacks is given. LÄS MER
