Two Classes of Power Mappings with Boomerang Uniformity 2

Zhen Li, Haode Yan

Let $q$ be an odd prime power. Let $F_{1} (x) = x^{d_{1}}$ and $F_{2} (x) = x^{d_{2}}$ be power mappings over $GF (q^{2})$ , where $d_{1} = q - 1$ and $d_2=d_1+\frac{q^2-1}{2}=\frac{(q-1)(q+3)}{2…

Boomerang Spectra of Two Classes of Power Functions via Their Differential Spectra

Ziying Zhang, Haode Yan, Zhen Li

In EUROCRYPT 2018, Cid $e t a l .$ introduced a new concept on the cryptographic property of S-boxes to evaluate the subtleties of boomerang-style attacks. This concept was named as…
