System and method thereof for processing cryptograph files

Abstract

The invention provides a system and a method thereof for processing cryptograph files. The system comprises a cryptograph decryption module, a clear text file acquisition module and a clear text file intelligent management module, wherein the cryptograph decryption module is used for decryption operation of the cryptograph files, decrypts cryptograph files into clear text files and then stores the clear text files into a secure directory; the clear text file acquisition module is used for acquiring the corresponding clear text files according to the request for acquiring the clear text files and according to a corresponding relation of the cryptograph and the clear text; and the clear text file intelligent management module is used for managing the produced clear text files, checking the using conditions of the clear text files, and deleting the corresponding clear text files according to the requirement. Through the system and the method, the performance of a terminal is furthest exerted under the limited resource conditions, and the clear text files can be cleared and deleted at proper time to reduce the space expense of the system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a system and method for processing ciphertext files. Background technique [0002] At present, most terminals usually use the following two methods for the use of ciphertext files (such as Digital Rights Management (DRM) files): (1) adopt the method of synchronous decryption and synchronous use; (2) use the ciphertext file Unified decryption to a plaintext file (the decrypted plaintext file is placed in an inaccessible directory, and the user does not know the whole process) and then used directly. [0003] Among them, the problem existing in the first method is that the performance of the system needs to be high, otherwise the user experience will be directly affected. [0004] The problem with the second method is that too many plaintext files will occupy the space of the system, so the total amount of files that can be supported is greatly limited; in addition, most of ...

AI Technical Summary

Problems solved by technology

[0003] Among them, the problem of the first method is that the performance of the system needs to be high, otherwise it will directly affect the user experience

[0004] The problem with the second method is that too many plaintext files will occupy the space of the system, so the total amount of files that can be supported is greatly limited; in addition, most of the ciphertext files cannot be directly stored in removable media, thus further limiting The scope of use of this method

And how to manage and use these decrypted files, there is no efficient and perfect solution for reference
