Abstract
A recent paper by Carlet introduces a general class of binary bent
functions on GF(2)n (n even)
whose elements are expressed by means of characteristic
functions (indicators) of
n/2-dimensional vector-subspaces of GF(2)n.
An extended version of this
class is introduced in the same paper; it is conjectured
that this version is coinciding with the whole class of
bent functions.
In the present paper, we prove that this conjecture is true.
