Vulnerability detection is an effective way to solve security problem of current industrial control system.By analyzing the difficulties of vulnerability detection in the existing industrial control platform,this paper proposes an improved fuzzing framework that introduces the concept of confidence to quantify the test cases as a classifier input,and thus pre-screens potential test cases,so as to reduce input space and enhance hit rate.Based on this architecture design for industrial control systems,the generic framework for vulnerability mining combines with malformed data structure,test target monitoring,and test results management,and supports multi-target,multi-protocol,multiplatform extensions.Finally,experimental results on an industrial controller have shown the feasibility and effectiveness of the method. 工业控制系统 Fuzzing 置信度 漏洞挖掘 industrial control system Fuzzing confidence vulnerability detection 10.14188/j.1671-8836.2013.05.014 TP273 国家自然科学基金（61173138,61272452）;国家自然科学基金青年基金（61003268）;湖北省重点新产品新工艺研究开发项目（2012BAA03004）资助项目 2013-05-01 2021-04-01 5 59
