Secret-related electronic file definite decryption method

Abstract

The invention relates to a secret-related electronic file definite decryption method, and belongs to the field of file definite decryption. The method comprises the following steps: S1, analyzing secret points of secret-related electronic files and collecting samples; S2, carrying out dense point keyword mining based on information gain; S3, constructing a dense point association rule base based on the knowledge graph; S4, constructing a knowledge graph fused with a military industry dense point rule set; and S5, performing intelligent matching comparison and rapid definite decryption. According to the invention, through an intelligent analysis technology, the accuracy and standardization of confidential electronic file decryption work are enhanced; the timeliness, the accuracy and the intelligence of electronic file security level relieving work are improved by utilizing an electronic file security point dynamic tracking means; through dense point comparison and an intelligent matching technology based on semantic analysis, real-time determination, intelligent change and timely decryption of the confidentiality level of the confidential electronic file are realized.

Description

technical field [0001] The invention belongs to the field of document determination and decryption, in particular to a method for determination and decryption of secret-related electronic files. Background technique [0002] Military secret-related networks are currently used in a wide range of state secret-related units. Although most of them are physically isolated from the wide area network, there are still phenomena such as high-density and low-level transmission, or high-density storage. At present, there are some monitoring methods that can be applied in some military secret-related networks. Scholars from Beijing Jiaotong University also do related work. The Fourth Academy of Aerospace also has a keyword-based dense point mining tool, which can perform dense point mining based on keyword matching. , to provide support for the decryption of classified electronic documents. [0003] Most of the existing dense point monitoring technologies are based on keyword matching ...
