Dynamic attack plane transformation method based on bidirectional control function

The invention discloses a dynamic attack plane transformation method based on bidirectional control function, wherein the method comprises the following steps: if the attack plane ASi of a system S ischanged, a new attack plane ASi+1 is obtained; the action of a certain resource r on the ASi is expressed as (formula); the action on the ASi+1 is expressed as (formula); the attack plane transfer definition is as follows: a system S and an environment Es thereof are given; the original attack plane of the system S is ASi, and the new attack plane is ASi+1; if at least one resource r exists, ther is an element of a set of (ASi\ASi+1) or (formula); and the attack plane of the system S is transferred. According to the dynamic attack plane transformation method based on the bidirectional control function in the invention, the attack difficulty of an attacker can be greatly improved by means of a dynamic attack plane mode; the attack cost of the attacker is increased; the transformation of the two-end roles of attack
