报告题目：Two new families of quadratic APN functions

报告摘要：In this talk, we will introduce two new families of APN functions. The first family is in bivariate form (x^3+xy^2+y^3+xy, x^5+x^4y+y^5+xy+x^2y^2). It is obtained by adding a special term to a known family of APN functions. The second family has the form L(z)^{2^m+1}+vz^{2^m+1} over F_{2^{3m}}, which generalizes a family of APN functions by Bracken et al. from 2011. In addition, the two new families cover two known sporadic APN instances over F_{2^8} and F_{2^9}, which were found by Edel and Pott in 2009 and by Beierle and Leander in 2021, respectively.
