Embodiment Construction

[0010] figure 1 The schematic diagram of the safety function block model is shown. The safety function block includes the safety function block input interface, output interface, safety algorithm module, execution control table, and internal data storage. When the safety service event arrives, the EPA safety trigger event passes through the safety function input The interface inputs the input terminal of the execution control table, and the EPA data flow is directly input into the security algorithm module, and the execution control table (ECC) calls the preset security algorithm strategy. The stream unsigned char (unsigned byte stream) is processed by the encryption / decryption algorithm to complete the encryption of the input data, and the formed EPA encrypted data stream is stored in the internal data storage, and the EPA encrypted data stream is output through the output interface of the security algorithm module. The output interface buffers and processes the encrypted res...

Abstract

This invention relates to one information safety method and its function module based on industry controlled network and to the safety management method, which comprises the following steps: establishing safety function module in the net; defining safety function module input interface and outputting interface and safety affairs and executing control form dispatching formula when the affairs arrive; processing the input unsigned char to fulfill the data coding and buffer the results in the output interface; finally executing the control form to send one affair signal and completing the coding formula in the key dispatching system.

Description

technical field [0001] The invention relates to a safety technology applicable to a network, in particular to a safety processing method and a safety control module of an industrial control network. Background technique [0002] The existing industrial control network design only adopts the existing information security technology to solve the security problem of industrial control network. With the increasing security threats and attacks on industrial control networks, these security technologies have been difficult to meet the requirements of heterogeneity, distribution, real-time, reliability and stability of industrial control networks. Contents of the invention [0003] The invention aims at the characteristics of heterogeneity and distribution of the industrial control network, and establishes a safe function block model in the industrial control network, and the key distribution of the safe encryption algorithm is completed during system configuration. The safety f...
