Embodiment Construction

[0022] Below is further detailed description of the present invention according to accompanying drawing and example:

[0023] figure 1 It is a schematic structural diagram of a security operation and maintenance architecture of an industrial control system according to the present invention. The architecture includes an authentication server and a BROKER server.

[0024] Further, the main functions of the authentication server are as follows:

[0025] (1) Responsible for user authentication, when the user needs to access the security operation and maintenance service cloud platform, first access the authentication server to perform user authentication, and if the authentication is successful, then feed back the token of the IoT device.

[0026] (2) Responsible for the certification of edge devices (sensors / actuators) newly deployed in industrial control systems. The edge device will report the ID number created by using blockchain technology to the authentication server. If...

Abstract

The invention discloses security operation and maintenance architecture of an industrial control system. With introduction of an authentication server and a BROKER server as well as a block chain technology and a stateless authentication technology, the real-time safety management system for field edge equipment like a sensor or an execution mechanism can be realized, so that the edge equipment and a client are in a loose coupling relationship. The BROKER server has functions of data forwarding, analysis and decision making. The traditional server-based security operation and maintenance architecture is no longer suitable for the current industrial control system environment. The security operation and maintenance architecture disclosed by the invention has advantages of high extendibility, flexibility, and reliability enables the information security of the industrial control system to be enhanced.

Description
