摘 要：Industrial control network security has become increasingly severe and has been highly *** paper studies the problems of low code coverage and relatively rough mutation strategies in the generation method of industrial control network protocol fuzzing test cases,and proposes a multidimensional mutation strategy-based fuzzing test ***,construct a multidimensional protocol field matrix according to the fields of the industrial control network protocol messages,and generate the corresponding variation factor matrix according to the characteristics of the ***,the agreement field matrix and the mutation factor matrix are processed by the Cartesian product to generate a multidimensional mutation *** strategy is used to guide the mutation of original data and test case ***,this method has undergone a comparative experiment on the Modbus/TCP *** results show that the proposed method not only improves the acceptance rate and coverage rate of test cases that generate malformed data,but also discovers two new zero-day vulnerabilities.
