Abstract
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 results on the (-)differential uniformity of functions that are not power functions. In this paper, we investigate the -differential uniformity of the swapped inverse functions in odd characteristic, and show that their -differential uniformities are at most 6 except for some special case.
