New Permutation Trinomials From Niho Exponents over Finite Fields with Even Characteristic
2016 · arXiv (Cornell University)
In this paper, a class of permutation trinomials of Niho type over finite fields with even characteristic is further investigated. New permutation trinomials from Niho exponents are obtained from linear fractional polynomials over finite fields, …

On the differential spectrum of a class of power functions over finite fields
2020 · arXiv (Cornell University)
Differential uniformity is a significant concept in cryptography as it quantifies the degree of security of S-boxes respect to differential attacks. Power functions of the form $F(x)=x^d$ with low differential uniformity have been extensively studied …

New Constructions of Optimal Linear Codes From Simplicial Complexes
2023 · IEEE Transactions on Information Theory
In this paper, we construct a large family of projective linear codes over${\mathbb F}_{q}$from the general simplicial complexes of${\mathbb F}_{q}^{m}$via the defining-set construction, which generalizes the results of [IEEE Trans. Inf. Theory 66(11):6762-6773, 2020]. The …
