关于弱APN函数与4位S盒

On weakly APN functions and 4-bit S-Boxes

Claudio Fontanari, Valentina Pulice, Anna Rimoldi, Massimiliano Sala

摘要:

S盒是分组密码的重要安全组成部分。我们提供的必要或充分的标准(可逆)4位S盒弱APN的理论结果。由于De Canniére和Leander-Poschmann独立实现了4位可逆S盒的分类,我们可以通过计算机辅助证明来加强我们的结果。

英文摘要:

S-Boxes are important security components of block ciphers. We provide theoretical results on necessary or sufficient criteria for an (invertible) 4-bit S-Box to be weakly APN. Thanks to a classification of 4-bit invertible S-Boxes achieved independently by De Canniére and Leander-Poschmann, we can strengthen our results with a computer-aided proof.
