On weak and strong 2k-bent Boolean functions
MetadataShow full item record
In this paper we introduce a sequence of discrete Fourier trans- forms and de ne new versions of bent functions, which we shall call (weak, strong) octa/hexa/2k-bent functions. We investigate relation- ships between these classes and completely characterize the octabent and hexabent functions in terms of bent functions.

Furthermore, bent functions are extremely ...
