论文摘要
在先前的论文\ cite {efrst20}中，我们两个，以及P. Ellingsen，P。Felke和A. Tkachenko，1DEDE定义了一个新的（输出）乘法差异，以及相应的$ C $ -Difterential均匀性，这具有扩展差异隐性分析的潜在。在这里，我们通过通过上述概念查看一些APN功能来继续工作，并表明其$ c $差异均匀性在某些情况下大大增加。
In a prior paper \cite{EFRST20}, two of us, along with P. Ellingsen, P. Felke and A. Tkachenko, 1defined a new (output) multiplicative differential, and the corresponding $c$-differential uniformity, which has the potential of extending differential cryptanalysis. Here, we continue the work, by looking at some APN functions through the mentioned concept and showing that their $c$-differential uniformity increases significantly, in some cases.
