20.500.12556/RUP-10034 Design methods for semi-bent functions Semi-bent functions play an important role in the construction of orthogonal variable spreading factor codes used in code-division multiple-access (CDMA) systems as well as in certain cryptographic applications. In this article we provide several infinite classes of semi-bent functions, where each class is characterized by either a different decomposition of such a function with respect to the Walsh spectra of its subfunctions, or by the method used for its derivation. In particular, we also give the exact number of possibilities of decomposing bent functions, in a subclass of the Maiorana-McFarland class. cryptography Boolean functions bent functions semi-bent functions derivatives kriptografija Boolove funkcije zakrivljene funkcije pol-zakrivljene funkcije derivati true true false Angleški jezik Angleški jezik Neznano 2018-12-19 07:31:18 2018-12-19 07:31:18 2024-03-01 13:50:39 0000-00-00 00:00:00 2019 0 0 str. 1-10 2019 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 51 0020-0190 25612800 10.1016/j.ipl.2018.12.002 1540928196 https://www.sciencedirect.com/science/article/pii/S0020019018302345 1 https://repozitorij.upr.si/Dokument.php?lang=slv&id=15793 Inštitut Andrej Marušič 0 0 0
