Abstract :
In this correspondence, the constructions and enumerations of all bent functions represented by a polynomial form of f(x)=Σi=1n2-1/ciTr(x1+2(i))+cn2/Tr1n 2/(x1+2(n2)/), ci∈2 F2 are presented for special cases of n. Using an iterative approach, the construction of bent functions of n variables with degree n/2 is also provided using the constructed quadratic bent functions.
