Geographic information data composite encryption system

Abstract

The invention discloses a geographic information data composite encryption system which is provided with an IT infrastructure layer, a data layer, a logic layer and an application layer from bottom totop, and the IT infrastructure layer is used for providing infrastructure for the system and guaranteeing normal operation of the system; the data layer is used for providing storage and query of a data file for the system, and the data file comprises a secret key and an operation log; wherein the logic layer is used for providing various interfaces for processing service logics in the application layer; the application layer is used for realizing composite encryption and decryption of geographic information data by using a hybrid encryption algorithm based on a local geographic information competent department encryption system and a weekly rate intelligent lock system; and the application layer comprises a composite encryption management module, a composite encryption password module, acomposite encryption authorization module, a composite encryption log module and a composite encryption function library module. The method has the remarkable effects that dual-system composite encryption of the geographic information data is realized, and the security of the geographic information data is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of geographical information data processing, in particular to a complex encryption system for geographical information data. Background technique [0002] In the Internet era, with the rapid development of information technology and the wide application of geographic information, the security management of confidential surveying and mapping geographic information is facing a severe situation. Some secret-related surveying and mapping geographic information production and use units have a weak sense of confidentiality, illegally store classified information on non-secret-related computers, and even send and transmit classified information on the Internet; cases of illegally obtaining, providing and buying and selling confidential surveying and mapping geographic information Occurs from time to time; cases of overseas organizations and individuals stealing important geographic information data of our country o...
