Embodiment

[0049]This embodiment provides a token-based anti-tampering method for industrial management network communication data. The method includes: before the engineer station sends communication data to the management network node, extracts the key information of the sent data and encodes it to generate text; The hash algorithm encrypts the text to generate a signature; the text and the signature form a token and send it together with the communication data; after the server receives it, it uses the built-in hash algorithm and the text in the token to generate a verification text; verifies the verification text and the token Whether the signature in the token matches, after matching, extract the key data of the received information and verify it with the Chinese text of the token, and prove that the communication data has not been tampered with after passing the verification.

[0050] Wherein, the token refers to a data packet describing the information to be sent, and the data pack...

Abstract

The invention belongs to the technical field of information security control, and provides a token-based industrial network data tamper-proofing method and a token-based industrial network data tamper-proofing system in order to solve the technical problem of unsafe data transmission in a DCS management network in the prior art. The method comprises the following steps that S1, a file is compiled,a token set F1 is formed through an encryption algorithm, and the token set F1 is uploaded to a real-time server; S2, the real-time server receives the token set F1 and judges whether the token set F1 meets preset requirements or not; after the token set F1 meets the requirement, the token set F1 is stored in a set list of the token set F1, and an engineer station is informed that the token set F1 is received completely; s3, the engineer station sends the file and the token set of the file to a real-time server in the form of a data packet, and the real-time server receives the file and the token set of the file; and S4, the real-time server judges whether the file and the token set of the file meet preset requirements or not, and if yes, subsequent file storage is continued.

Description

technical field [0001] The present invention relates to the technical field of information security control, in particular to the technical field of security control of data transmission in a nuclear power DCS system; more specifically, to a token-based industrial network data tamper-proof method and system. Background technique [0002] In the field of industrial control, especially in the management network of a nuclear power DCS system (Distributed Control System, distributed control system), there are usually multiple equipment nodes such as an engineer station, an operator station, a gateway, a real-time server, and a history server; specifically, such as figure 1 shown. [0003] The inventor found in the process of realizing the present invention: in the DCS system in the prior art, it is one of the basic functions for each device node to realize file data transmission and reception. In order to realize this function, a remote file service is installed in each device. ...
