• Analysis of Trivium Using Compressed Right Hand Side Equations 

      Schilling, Thorsten Ernst; Raddum, Håvard (Chapter; Peer reviewed, 2012)
      We study a new representation of non-linear multivariate equations for algebraic cryptanalysis. Using a combination of multiple right hand side equations and binary decision diagrams, our new representation allows a very ...
    • Solving Compressed Right Hand Side Equation Systems with Linear Absorption 

      Schilling, Thorsten Ernst; Raddum, Håvard (Chapter; Peer reviewed, 2012)
      In this paper we describe an approach for solving complex multivariate equation systems related to algebraic cryptanalysis. The work uses the newly introduced Compressed Right Hand Sides (CRHS) representation, where equations ...
    • Solving Equation Systems by Agreeing and Learning 

      Schilling, Thorsten Ernst; Raddum, Håvard (Chapter; Peer reviewed, 2010)
      We study sparse non-linear equation systems defined over a finite field. Representing the equations as symbols and using the Agreeing algorithm we show how to learn and store new knowledge about the system when a ...
