与3类向量值密码函数仿射等价的函数数量研究
Research on affine equivalence enumeration of the three families vectorial function
摘要
Abstract
In recent years, Qu-Tan-Tan-Li function, Zha-Hu-Sun function and Tang-Carlet-Tang function have been pro-posed 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 253[8Πi=1(2i-1]2cryptographic functions of affine equivalent to the Zha-Hu-Sun function over finite field GF(28), which can be chosen as S-boxes of block ciphers.关键词
