AI Technical Summary

Technical Problem

Existing data encoding technologies such as LZW encoding have poor security in encrypting ballistic calculation data and cannot effectively hide original data information, resulting in a high risk of leakage of national defense secrets.

Method used

By obtaining the initial data, a character combination sequence and a temporary index table are constructed, the frequency of occurrence of character combinations is counted, character combinations with great influence are merged, character combinations are disassembled and updated, an optimized index table is established for encoding and encryption, and a secondary index sequence is used to improve the encryption effect.

Benefits of technology

It improves the encryption security of ballistic calculation data, ensures the information hiding effect in the data management process, and enhances the protection of national defense secrets.

Abstract

The present invention relates to the technical field of data encryption processing, and in particular to a method for intelligent management of trajectory calculation data, the method comprising: obtaining data before and after calculation by trajectory software as original data to be managed; selecting data from the original data as initial data; obtaining a character combination sequence and a temporary index table of the initial data, and counting the frequency of occurrence of each character combination in the character combination sequence in the original data as the influence degree of the corresponding character combination; obtaining new characters in the original data, and obtaining an updated character combination based on the new characters and the influence degree of each character combination; disassembling the updated character combination to obtain at least two decomposed character combinations, and obtaining a secondary index sequence of the updated character combination in combination with the original data to obtain an optimized index table; encoding and encrypting the original data according to the optimized index table to obtain ciphertext data for management, thereby improving the data encryption effect and information hiding, and ensuring data security.
