Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] The platform of the present invention is jointly realized by the industrial control terminal and the management server, such as figure 1 shown. The industrial control terminal uses the client program to coordinate and manage the system functions in a unified manner. In order to enhance the portability and expansibility of the system, the management server interacts with the administrator in the form of web service calls. If a new module needs to be added, it only needs to provide the corresponding web service interface. When the embodiment is deployed in an actual industrial control system, the industrial control terminal is located at each engineer operation station, and each operation station is installed with industrial control software and programs to directly control the industrial control system equipment modules connected to it...

Abstract

The invention provides an industrial control system trusted environment control method and platform based on a safety chip. The method comprises the steps: (1) registering an industrial control terminal to a management server on the basis of the safety chip; (2) carrying out complete measurement on each operating process by adopting the industrial control terminal; (3) checking the measurement information by the management party on the management server, and forming a white list; (4) downloading the white list formed by the management party from the management server by the industrial control terminal, leading the white list into an operating system core, and then carrying out the control on the process to be operated. By adopting the method and platform, malicious code of an untrusted, unknown and uncontrollable program process is prevented from damaging the system of the industrial control terminal, from stealing the confidential information and damaging the industrial production, so that the safety defense capacity of the industrial control system can be improved.

Description

technical field [0001] The present invention relates to a trusted environment management and control method and platform for industrial control systems (hereinafter referred to as industrial control systems), in particular to a trusted environment management and control method and platform for trusted industrial control systems based on secure hardware and integrity protection methods, and belongs to the field of information security. Background technique [0002] With the rapid development and evolution of new computer viruses, malicious codes and intrusion methods, industrial control systems have gradually become the target of targeted attacks and are facing increasing security threats. Establishing a trusted environment management and control platform for industrial control systems can effectively improve the defense capabilities of industrial control terminals (hereinafter referred to as industrial control terminals) and ensure the normal operation of industrial equipment...
