Differential Spectrum of Some Power Functions With Low Differential Uniformity

Sung-Tai Choi, Seokbeom Hong, Jong-Seon No +1

In this paper, for an odd prime $p$, the differential spectrum of the power function $x^{\frac{p^k+1}{2}}$ in ${\mathbb{F}}_{p^n}$ is calculated. For an odd prime $p$ such that $p\eq…
