New construction of Boolean functions with maximun algebraic immunity

Wang yongjuan and Fan shuqin and Han wenbao

Abstract: Because of the algebraic attacks, a high algebraic immunity is now an important criteria for Boolean functions used in stream ciphers. In this paper, by using the relationship between some flats and support of a n variables Boolean function f, we introduce a general method to determine the algebraic immunity of a Boolean function and finally construct some balanced functions with optimum algebraic immunity.
