• Algebraic Attack on Small Scale Variants of AES using Compressed Right Hand Sides 

      Indrøy, John Petter (Master thesis, 2018-04-07)
      The Advanced Encryption Standard is probably the most used symmetric encryption cipher in use today, which makes it particularly interesting for cryptanalysis. This thesis attacks smallscale variants of AES through a ...
    • Linear dependencies between non-uniform distributions in DES 

      Fauskanger, Stian (Master thesis, 2014-05-30)
      Davies and Murphy explained some non-uniform distributions of the output from pairs and triplets of S-boxes in DES, and how they are completely dependent on some key bits. There are linear dependencies between these ...
    • Statistical and Algebraic Properties of DES 

      Fauskanger, Stian; Semaev, Igor A. (Lecture Notes in Computer Science ; 9589, Chapter, 2016)
      D. Davies and S. Murphy found that there are at most 660 different probability distributions on the output from any three adjacent S-boxes after 16 rounds of DES. In this paper it is shown that there are only 72 different ...
