CCZ-inequivalent representatives from the known APN families for dimensions up to 11

From Boolean
Jump to navigation Jump to search

The following table presents CCZ-inequivalent representatives from all CCZ-equivalence classes corresponding to the known infinite families of APN power functions over GF(2^n) and the known infinite families of quadratic APN polynomials over GF(2^n) over GF(2n) for n from 6 to 11. Values of various invariants are given in the cases when this is possible; empty cells in the invariant columns indicate that their computation is infeasible using our current resources.

Note: In dimension 10, not all instances of family C11 have been checked. The ones that we have checked are CCZ-equivalent to the representatives currently given in the table above, but, at the moment, we cannot assert that the representatives from the table exhaust all possible CCZ-classes corresponding to C11 in dimension 10.
