On constructing special apn functions and their link with apn permutations

The existence of APN permutation in even dimension is an important open problem on cryptographic Boolean functions. In this paper, we consider an algorithm for constructing 2-to-1 APN functions and searching the corresponding affine functions such that their sum is an APN permutation. As a result, 2-to-1 APN functions in 5 and 6 variables are found. These functions are APN permutations.
