Abstract:

Based on the properties of the 2-tuples distribution matrix of the rotation symmetric orbits, all 7-variable 2-resilient rotation symmetric Boolean functions were constructed concretely.The results show that there are only 280 nonlinear 2-resilient rotation symmetric Boolean functions over F 2 7 .Furthermore, there are at least 280 nonlinear 2-resilient rotation symmetric Boolean functions over F 2 7k for any odd number k.

Key words: cryptography, rotation symmetric function, resilient function, support matrix, 2-tuples distribution matrix
