Research on affine equivalence enumeration of the three families vectorial function
Zha-Hu-Sun function and Tang-Carlet-Tang function have been proposed with differential uniformity 4 and many good cryptographic properties.the counting problem of affine equivalent to the three families cryptographic functions was investigated.By using some properties of finite fields
the upper and lower bound of the number of affine equivalent to the Zha-Hu-Sun function
and the upper bound of the number of affine equivalent to the Qu-Tan-Tan-Li function and Tang-Carlet-Tang function were computed
respectively.Moreover
a conjecture was given about the exact number of affine equivalent to the Zha-Hu-Sun function.Results show that there are at least
cryptographic functions of affine equivalent to the Zha-Hu-Sun function over finite field GF(2
8
)
which can be chosen as S-boxes of block ciphers.
