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…
Finding compositional inverses of permutations from the AGW criterion
Tailin Niu, Kangquan Li, Longjiang Qu +1
Permutation polynomials and their compositional inverses have wide applications in cryptography, coding theory, and combinatorial designs. Motivated by several previous results on…
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…
