Modbus protocol vulnerability mining method based on dynamic taint analysis

The invention belongs to the technical field of dynamic taint analysis, and particularly relates to a Modbus protocol vulnerability mining method based on dynamic taint analysis. The Modbus protocol vulnerability mining method solves the problem that current fuzzy testing is low in efficiency, designs a Modbus protocol key field positioning method by using a dynamic stain analysis technology, positions a key field in a Modbus protocold, and combines a fuzzy testing technology, so that the test case generated by fuzzy testing is more targeted, and the efficiency of vulnerability mining for the Modbus protocol is effectively improved. 本发明属于动态污点分析技术领域，具体涉及一种基于动态污点分析的Modbus协议漏洞挖掘方法。本发明解决了目前模糊测试效率较低的问题，使用动态污点分析技术设计出一种Modbus协议关键字段定位方法，通过对Modbus协议中关键字段进行定位，与模糊测试技术相结合，可以使模糊测试生成的测试用例更具有针对性，进而有效的提高针对Modbus协议进行漏洞挖掘的效率。
