Problems solved by technology

Among these three types of solutions, they can only one-sidedly solve the security problems caused by a certain intrusion method in the entire industrial control system, but for unknown threats such as unknown loopholes and unknown backdoors, it is much weaker.

Embodiment 1

[0026] Embodiment one, such as figure 1 As shown, the project file full lifecycle security protection method of the present invention includes four stages: project file compilation link, project file transmission link, project file storage link and project file operation link. In each link, based on heterogeneous redundancy, Redundancy voting mechanism, combined with the specific process to increase the corresponding security protection technology to form an information security protection plan, specifically includes the following steps:

[0027] Step 1, such as figure 2 As shown, the intermediate code of the cross-platform environment is generated based on the basic environment of the heterogeneous multi-mode lower computer software and hardware; in the process of compiling the logic configuration project file, multiple target operating platforms are used to generate multiple highly confusing and functionally equivalent Logical configuration project files;

Abstract

The invention relates to the automatic control information safety protection technology field, especially relates to an engineering document full life cycle safety protection method. By taking a heterogeneous redundancy voting technology as a core, the engineering document full life cycle safety protection method is combined with the concrete flows and the concrete technologies of the compiling link, the transmission link, the storage link, and the operation link of the engineering document full life cycle. Heterogeneous polymorphs of engineering documents generated in the compiling link do not have any consistent available attack paths, cannot be attached by any intermediaries in the transmission link, and cannot be tampered in the storage link, and in addition, attacks on the heterogeneous polymorphs of the engineering documents are invalid, and finally, an object of protecting the engineering documents in a flow is achieved, and therefore the confidentiality, the integrity, and the availability of the logical configuration engineering documents are enhanced, and threats on unknown loopholes and unknown backdoors are effectively prevented.

Description

technical field [0001] The invention relates to the technical field of automatic control information security protection, in particular to a method for security protection of the entire life cycle of engineering documents. Background technique [0002] Industrial control systems are widely used in the field of industrial automation and control, such as national infrastructure such as electric power, petroleum, and national defense technology, as well as people's livelihood fields such as food, medicine, and transportation. However, at the beginning of the construction of the industrial control system, more considerations were given to physical safety and functional safety. The system architecture design was only to realize automation and information-based control functions, which facilitated production and management, and lacked information security considerations and construction. With the deep integration of industry and informatization, the introduction of Industry 4.0, a...
