The Design of Boolean Functions by Modified Hill Climbing Method
Yuriy I. Izbenko, Vladislav Kovtun, Alexandr Alexandrovich Kuznetsov · 2009
With cryptographic investigations, the design of Boolean functions is a wide area. The Boolean functions play important role in the construction of a symmetric cryptosystem. In this paper the modified hill climbing method is considered. Using hill climbing techniques, the method allows modifying bent functions used to design balanced, highly non-linear Boolean functions with high algebraic degree and low autocorrelation. The experimental results of constructing the cryptographically strong Boolean functions are presented.
