    • Decomposing Linear Layers 

      Beierle, Christof; Felke, Patrick; Leander, Gregor; Rønjom, Sondre (Journal article; Peer reviewed, 2022)
      There are many recent results on reverse-engineering (potentially hidden) structure in cryptographic S-boxes. The problem of recovering structure in the other main building block of symmetric cryptographic primitives, ...

    • The Legendre Symbol and the Modulo-2 Operator in Symmetric Schemes over Fnp: Preimage Attack on Full Grendel 

      Grassi, Lorenzo; Khovratovich, Dmitry; Rønjom, Sondre; Schofnegger, Markus (Journal article; Peer reviewed, 2022)
      Motivated by modern cryptographic use cases such as multi-party computation (MPC), homomorphic encryption (HE), and zero-knowledge (ZK) protocols, several symmetric schemes that are efficient in these scenarios have recently ...
