Generalizations of bent functions
Bent functions (Boolean functions with extremal nonlinear properties) are intensively studied at present since they have numerous applications in cryptography, coding theory, and other areas. New statement of problems lead to appearance of many new generalizations of bent functions which are not well known to the specialists in Boolean functions. In the paper, a systematic survey of them is given.
Keywords: Boolean function, the Walsh–Hadamard transform, nonlinearity, bent function, CDMA.
