This paper surveys techniques for studying and constructing balanced Boolean functions that exhibit desirable nonlinear properties including high nonlinearity, good avalanche characteristics and high orders of correlation immunity. Emphasis is placed on techniques that are of combinatorial nature, especially those that utilize extensively Hadamard matrices and hypergraphs.
