    • Five-weight codes from three-valued correlation of M-sequences 

      Shi, Minjia; Qian, Liqin; Helleseth, Tor; Sole, Patrick (Journal article; Peer reviewed, 2023)
      In this paper, for each of six families of three-valued m-sequence correlation, we construct an infinite family of five-weight codes from trace codes over the ring R = F2 + uF2, where u2 = 0. The trace codes have the ...

    • Some group-theoretical results on Feistel Networks in a long-key scenario 

      Aragona, Riccardo; Calderini, Marco; Civino, Roberto (Journal article; Peer reviewed, 2020)
      The study of the trapdoors that can be hidden in a block cipher is and has always been a high-interest topic in symmetric cryptography. In this paper we focus on Feistel-network-like ciphers in a classical long-key scenario ...
