On non-monomial APcN permutations over finite fields of even characteristic
Jaeseong Jeong, Namhun Koo, Soonhak Kwon
Recently, a new concept called the -differential uniformity was proposed by Ellingsen et al. (2020), which allows to simplify some types of differential cryptanalysis. Since the…

Low c-Differential Uniformity of the Swapped Inverse Function in Odd Characteristic
Jaeseong Jeong, Namhun Koo, Soonhak Kwon
The study of Boolean functions with low -differential uniformity has become recently an important topic of research. However, in odd characteristic case, there are not many resu…

Investigations of c-Differential Uniformity of Permutations with Carlitz Rank 3
Jaeseong Jeong, Namhun Koo, Soonhak Kwon
The -differential uniformity is recently proposed to reflect resistance against some variants of differential attack. Finding functions with low -differential uniformity is a…
