CONSTRUCTING NEW APN FUNCTIONS FROM KNOWN PN FUNCTIONS
Zhengbang Zha, Lei Hu · International Journal of Foundations of Computer Science · 2013
We present a method for constructing almost perfect nonlinear (APN) functions in odd characteristic by modifying some values of known perfect nonlinear functions. As a consequence, new APN polynomial functions such as ones over 𝔽13 which are CCZ-inequivalent to known APN functions are obtained.
