Encryption and decryption method for module

Abstract

The invention relates to an encryption and decryption method for a module, which comprises the following steps of: attempting to load all the newly started applications in a dynamic link library (DLL) way through a system registry key by a user; 2, identifying the current application to determine the type of the application; 3, communicating with a collaboration service to determine whether the current application is a security application or not; 4, if the current application is the security application, then determining whether the current application has a mapping plaintext file or not; 5, using the ciphertext; 6, checking whether the ciphertext is in a list or not when the plaintext Handle is closed; and 7, exiting the program. The encryption and decryption method for the module of the invention has higher scalability on a new application format and can support the transparent decryption of the ciphertext to determine the working way as manual encryption or automatic encryption, cooperate with modules such as a multi-document module, and the like to carry out content access control, uniformly misarrange, reduce the customized number of the current code and transfer the customized items of a project to other peripheral modules to the greatest extent. The encryption and decryption method for the module has high maintainability.

Description

technical field [0001] The invention relates to an encryption and decryption method, in particular to a module encryption and decryption method. Background technique [0002] At present, a shared key generation method in the prior art includes generating a random seed group, randomly taking two of them as edge random seeds, representing the two sides of a triangle; taking the other as an angle random seed, representing the Angle; use the length of the third side of the triangle formed by the above random seed as the shared key. This prior art also includes an encryption method, including generating a side random seed, representing two sides of a triangle; generating an angle random seed, representing an angle between the two sides; mapping the plaintext into an angle set, the angle represented by each element in the set Represents the angle between two sides, and calculates the length of the third side of the encrypted triangle formed by each angle in the angle set and the ...

AI Technical Summary

Problems solved by technology

[0006] 1. The encryption and decryption method based on the user identity in the prior art is based on the user identity, so the scope of use is narrow and the use is more restricted

[0007] 2. The code of the encryption and decryption method based on the user ID in this prior art has low readability and maintainability, and poor stability

[0008] 3. This prior art encryption and decryption method based on user identity identification has poor scalability for new application formats, and has no functions such as access control and unified troubleshooting.
