On two conjectures about the intersection distribution
Yubo Li, Kangquan Li, Longjiang Qu
Recently, S. Li and A. Pott\cite{LP} proposed a new concept of intersection distribution concerning the interaction between the graph $\{(x,f(x))~|~x\in\F_{q}\}$ of and the lin…
A complete characterization of the APN property of a class of quadrinomials
Kangquan Li, Chunlei Li, Tor Helleseth +1
In this paper, by the Hasse-Weil bound, we determine the necessary and sufficient condition on coefficients with such that $f(x) = {x}^{3\cd…
Binary linear codes with few weights from two-to-one functions
Kangquan Li, Chunlei Li, Tor Helleseth +1
In this paper, we apply two-to-one functions over in two generic constructions of binary linear codes. We consider two-to-one functions in two forms: (1) general…
Further Study of Planar Functions in Characteristic Two
Yubo Li, Kangquan Li, Longjiang Qu +1
Planar functions are of great importance in the constructions of DES-like iterated ciphers, error-correcting codes, signal sets and the area of mathematics. They are defined over f…
Cryptographically Strong Permutations from the Butterfly Structure
Kangquan Li, Chunlei Li, Tor Helleseth +1
In this paper, we present infinite families of permutations of with high nonlinearity and boomerang uniformity from generalized butterfly structures. Both…
Further study of -to- mappings over
Kangquan Li, Sihem Mesnager, Longjiang Qu
-to- mappings over finite fields play an important role in symmetric cryptography, in particular in the constructions of APN functions, bent functions, semi-bent functions an…
