The invention relates to a communication method and system for an industrial control network. The method is applied to an industrial control equipment sequence in the industrial control network. The method comprises the following steps: terminating industrial control equipment in an industrial control equipment sequence determines a target working state identifier set corresponding to the industrial control equipment sequence, wherein the target working state identifier set comprises a target working state identifier of each piece of industrial control equipment in the industrial control equipment sequence, and the target working state identifier of any piece of industrial control equipment is used for indicating the current working state of the industrial control equipment; the terminating industrial control equipment encrypts the target working state identifier set and address information of the terminating industrial control equipment to determine a first ciphertext; and the termination industrial control equipment sends the first ciphertext to control terminal equipment . According to the invention, the working state of each industrial control equipment can be timely, rapidlyand accurately determined, and the attack resistance of the communication process can be improved through the ciphertext communication mode.
Description
Technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a communication method and system for industrial control networks. Background technique [0002] Safety production has always been the guiding core of the operation and development of my country's industrial enterprises. The daily production and operation of production enterprises cannot do without the support of various large-scale electromechanical equipment, and the safe operation of these equipment is of great significance to the enterprise. The normal operation of industrial control equipment in the industrial control network is directly related to the continuity of the industrial production line. If the safety of the industrial control equipment is not guaranteed, it may cause the stagnation of the entire industrial production work and adversely affect the operation and development of the enterprise. Therefore, timely and accurate determination of the working stat...
