Embodiment 1

[0045] This embodiment provides an identification system for industrial control equipment, such as figure 1 As shown, the identification system 1 may include an information collection module 11 and a certificate generation module 12;

[0046] The information collection module 11 is used to collect hardware information for uniquely identifying the industrial control equipment. The hardware information may include but not limited to CPU (Central Processing Unit) serial number and network card address. The industrial control equipment includes at least one of an engineer station, a man-machine interface station, a historical data server, a report server, a controller, and a network switch. The controller can control valves, pumps, currents, pressures, and switches, among others.

[0047] The certificate generating module 12 is used for encrypting the hardware information to generate a digital signature certificate.

[0048] Specifically, the hardware information may be encrypt...

Embodiment 2

[0066] This embodiment provides an identification system for industrial control equipment, such as figure 2 As shown, the identification system is a further improvement on the basis of Embodiment 1.

[0067] In order to further enhance the credibility of industrial control equipment certification, a combination of digital signature certificate verification and hash value (Hash) verification can be used.

[0068] Specifically, the identification system 1 may also include a hash value calculation module 15, the hash value calculation module 15 is used to perform hash calculation on the hardware information to generate a corresponding hash value, and the The hash value is sent to the industrial control equipment; when the digital signature certificate passes the verification of the authentication module 13, the authentication module 13 is also used to verify the hash value; if the verification is passed, then confirm The industrial control device is a trusted device; if the ver...

Embodiment 3

[0075] This embodiment provides an identification method for industrial control equipment, such as image 3 As shown, the identification method may include the following steps:

[0076] Step S1: collecting hardware information for uniquely identifying the industrial control device.

[0077] The hardware information may include but not limited to CPU (Central Processing Unit) serial number and network card address. The industrial control equipment includes at least one of an engineer station, a man-machine interface station, a historical data server, a report server, a controller, and a network switch. The controller can control valves, pumps, currents, pressures, and switches, among others.

[0078] Step S2: Encrypt the hardware information to generate a digital signature certificate. Specifically, the hardware information may be encrypted by SM2 national secret algorithm or SM3 national secret algorithm.

[0079] Further, after the step S2, it may also include:

Abstract

The invention discloses an identification system and method for industrial control equipment, a medium and electronic equipment. The identification system comprises an information acquisition module and a certificate generation module. The information acquisition module is used for acquiring hardware information for uniquely identifying the industrial control equipment. The certificate generationmodule is used for encrypting the hardware information to generate a digital signature certificate. According to the invention, the digital signature certificate can be generated by utilizing the hardware information uniquely identifying the industrial control equipment before the equipment leaves a factory; and the identity or the source of the industrial control equipment can be identified through the digital signature certificate, so that the identification accuracy is improved, illegal equipment is effectively prevented from being disguised as legal equipment, and the information securityof an industrial control system is guaranteed.

Description

technical field [0001] The invention relates to the field of digital authentication, and specifically relates to an identification system, method, medium and electronic equipment for industrial control equipment. Background technique [0002] With the rapid development of computer and network technology, the scale of distributed industrial control systems (such as: nuclear power plant control systems, wind farm control systems, etc.) importance is also becoming more apparent. After the distributed industrial control system leaves the factory, it is usually maintained by the user who purchased the control system. During the use, the user sometimes replaces or changes the discrete devices in the system without permission. The changed device may cause viruses. The program is mixed into the whole system, resulting in the theft of important operating data, which poses a great threat to the security of the operation of the distributed industrial control system. [0003] In the p...
