Title: Method for generating malicious sample of industrial control system based on adversarial learning
Inventor: CHENG PENG
IPC: G06K9/62
Filed: 2019-08-18
Abstract: Disclosed is a method for generating a malicious sample of an industrial control system based on adversarial learning. In the method, by means of adversarial learning technology, an adversarial sample of an industrial control intrusion detection system based on a machine learning method is calculated by using an optimization solution. A corresponding new adversarial sample can be generated after an attack sample that can originally be found by the intrusion detection system is processed by means of the method. The adversarial sample can bypass an original intrusion detector (recognized to be normal), and still maintains an attack effect. The present invention effectively guarantees the security of an industrial control system by means of actively generating a malicious sample of the industrial control system, thereby taking preventive measures.
