Abstract. In this paper, we study GF-NLFSR, a Generalized Unbalanced Feistel Network (GUFN) which can be considered as an extension of the outer function FO of the KASUMI block cip...
DeKaRT primitives are key-dependent reversible circuits presented at CHES 2003. According to the author, the circuits described are suitable for data scrambling but also as buildin...
This paper shows that the actual proposal for an unbalanced Feistel network by Schneier and Blaze is as vulnerable to differential cryptanalysis as the DES. 1 McGuffin Schneier and...
In this paper we are interested in algebraic immunity of several well known highly-nonlinear vectorial Boolean functions (or Sboxes), designed for block and stream ciphers. Unfortu...
