Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0029] The so-called symbolic execution is to use symbolic values ​​instead of real values ​​to execute. It is an important formal method and software analysis technology. Its main platform is Selective Symbolic Execution, S2E platform. By using symbolic execution technology, the values ​​​​of variables in the program are Expressed as a calculation expression...

Abstract

The invention discloses an intelligent fuzzy test method, device and system, and relates to the technical field of computers, and the method comprises the steps: converting an input variable of a tested target into a symbolic expression through symbolic execution; performing execution path constraint on the symbolic expression of the multiple paths of input variables; generating a test case according to the constrained execution path; and executing the test case, and obtaining an execution state and test data of the test case. The embodiment of the invention can solve the problem of low detection efficiency of the existing fuzzy test.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an intelligent fuzz testing method, device and system. Background technique [0002] Due to the existence of design loopholes and software loopholes in the power system, malicious attacks against the power cyber-physical system (power CPS) implemented from the information side are likely to break through the protection measures and cause larger-scale disturbances and failures. Therefore, it is extremely necessary for the protection of electric power CPS to discover the loopholes in the current electric power CPS protocol and system. [0003] At present, the security vulnerability detection methods of the Internet of Things have become mature, and various technologies can also be used in the vulnerability detection of electric power CPS. The vulnerability detection technologies are mainly divided into static analysis and dynamic analysis. The object of static analysis is mainly ...
