In a previous paper, we have obtained a characterization of thebinary bent functions on (GF(2))^n (n even) as linearcombinations modulo 2^n/2, with integral coefficients, ofcharacteristic functions (indicators) of n/2-dimensional vector-subspaces of(GF(2))^n. There is no uniqueness of the representation of agiven bent function related to this characterization. We obtain now a newcharacterization for which there is uniqueness of the representation.
