Abstract: This paper researches the number of annihilators of a Boolean function, gives a new way to take count of the independent annihilators based on the coefficient matrix of a Boolean function. It presents the concept of low annihilators of a Boolean function, and gives a way to find them based on the new way of counting the independent annihilators of a Boolean function. It depicts the attack notion by using the low annihilators of a Boolean function to establish an equation group.

Key words: algebraic attack, algebraic immunity, low annihilators of Boolean functions
