| Abstract | This paper gives a construction method which can get a large class of Boolean functions with maximum algebraic immunity(AI) from one such giving function. Our constructions get more functions than any previous construction. The cryptographic properties, such as balance, algebraic degree etc, of those functions are studied. It shows that we can construct Boolean functions with better cryptographic properties, which gives the guidance for the design of Boolean functions to resist algebraic attack, and helps to design good cryptographic primitives of cryptosystems. From these constructions, we show that the count of the Boolean functions with maximum AI is bigger than ${2^{2^{n-1}}}$ for $n$ odd, bigger than ${2^{2^{n-1}+\frac{1}{2}\binom{n}{\frac{n}{2}} }}$ for $n$ even, which confirms the computer simulation result that such boolean functions are numerous. As far as we know, this is the first bound about this count. |
