Abstract

The invention provides a communication method and device of an industrial security gateway based on an embedded system, and aims to enhance the security of data transmission in an industrial control network. The method comprises the following steps: acquiring data information of an industrial field; performing encryption and digital signature processing on the acquired data information through a selected and/or customized encryption algorithm; and transmitting the encrypted data information and generated digital signature information to a server side. The device comprises an acquisition unit for acquiring the data information of the industrial field, an encryption unit for performing encryption and digital signature processing on the acquired data information through the selected and/or customized encryption algorithm, and a first transmission unit for transmitting the encrypted data information and generated digital signature information to the server side. The communication method and device are suitable for 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 for an industrial security gateway based on an embedded system. Background technique [0002] In traditional industrial production, the data on the industrial site, such as equipment operating status parameter information, is obtained through disk copying or manual transmission (such as: manual meter reading, periodic 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 network for production control and information management. [0003] Today, industrial control networks composed of various embedded devices have widely penetrated into scientific research, engineering design, military technology, and people's daily life. The realization of the interconnection between embedded devices and in...
