[Resource Topic] 2019/873: Count of rotational symmetric bent Boolean functions

Welcome to the resource topic for 2019/873

Title:
Count of rotational symmetric bent Boolean functions

Authors: Shashi Kant Pandey, P. R. Mishra

Abstract:

Counting the Boolean functions having specific cryptographic features is an interesting problem in combinatorics and cryptography. Count of bent functions for more than eight variables is unexplored. In this paper, we propose an upper bound for the count of rotational symmetric bent Boolean functions and characterize its truth table representation from the necessary condition of a rotational symmetric bent Boolean function.
