Locally-APN Binomials with Low Boomerang Uniformity in Odd Characteristic
Namhun Koo, Soonhak Kwon, Minwoo Ko +1
Recently, several studies have shown that when , for certain choices of , the function defined over $\Fq$ is locally-APN and h…
On Differential and Boomerang Properties of a Class of Binomials over Finite Fields of Odd Characteristic
Namhun Koo, Soonhak Kwon
In this paper, we investigate the differential and boomerang properties of a class of binomial over the finite field , where $r = \f…
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…
On the Boomerang Uniformity of Permutations of Low Carlitz Rank
Jaeseong Jeong, Namhun Koo, Soonhak Kwon
Finding permutation polynomials with low differential and boomerang uniformityis an important topic in S-box designs of many block ciphers. For example, AES chooses the inverse fun…
