A communication method and device for an industrial security gateway based on an embedded system

Abstract

The invention provides a communication method and device of an industrial security gateway based on an embedded system, which helps to improve the security of data transmission in an industrial control network. The method includes: obtaining data information on an industrial site; performing encryption and digital signature processing on the obtained data information through a selected and / or customized encryption algorithm; sending the encrypted data information and the generated digital signature information to to the server. The device includes: an acquisition unit, used to acquire data information on an industrial site; an encryption unit, used to encrypt and digitally sign the acquired data information through a selected and / or customized encryption algorithm; a first sending unit, It is used to send the encrypted data information and the generated digital signature information to the server. The invention is applicable to the technical field of industrial automation information security.

Description

Technical field [0001] The invention relates to the technical field of industrial automation information security, in particular to a communication method and device of an industrial security gateway based on an embedded system. Background technique [0002] In traditional industrial production, data on the industrial site, such as equipment operating state parameter information, is obtained through copying or manual transfer (such as manual meter reading, regular report reporting). These traditional methods are difficult to meet the long-term, large-data volume, real-time monitoring and accuracy requirements of today's industrial control networks for production control and information management. [0003] Nowadays, the industrial control network composed of various embedded devices has widely penetrated into all aspects of scientific research, engineering design, military technology, and people’s daily life. Realizing the interconnection of embedded devices and information network...
