The fast Walsh transform can be used to efficiently generate samples using this model.
2.
The "'partially bent functions "'form a large class defined by a condition on the Walsh transform and autocorrelation functions.
3.
The Walsh matrix ( and Walsh functions ) are used in computing the Walsh transform and have applications in the efficient implementation of certain signal processing operations.
4.
By 1988 Forr?recognized that the Walsh transform of a function can be used to show that it satisfies the Strict Avalanche Criterion ( SAC ) and higher-order generalizations, and recommended this tool to select candidates for good S-boxes achieving near-perfect " balanced"
