Non-inductive encryption and decryption method based on macOS system

Abstract

The invention discloses a non-inductive encryption and decryption method based on a macOS system. The method comprises the following steps: building a kernel extension module, and enabling the kernelextension module to be mounted in an macOS system; constructing a security policy, registering character equipment, and inputting the security policy into the kernel extension module through characterequipment; identifying file data to be processed; replacing a system function needing to be processed by the macOS system with a security function address according to the security policy; determining credit extension software, malicious software and common software according to the safety strategy, performing safety logic processing according to the software type. Manual encryption and decryption are not needed when the software is adopted to open the file, operation is non-inductive and transparent, and a good confidentiality effect on the file is achieved.

Description

technical field [0001] The invention relates to the field of encryption, in particular to a non-sensing encryption and decryption method based on macOS system. [0002] technical background [0003] In the current macOS system, in order to prevent the leakage of confidential files, it is usually necessary to encrypt the confidential files and save them on the hard disk. The encryption method is usually manual encryption, which needs to be manually decrypted before use. The decryption operation is cumbersome. The file is a plaintext file, and malicious software can easily obtain the plaintext file on the hard disk, thereby increasing the risk of leakage. Contents of the invention [0004] One of the purposes of the present invention is to provide a non-sensing encryption and decryption method based on macOS system. According to the technical effect of realizing non-sensing and transparent encryption and decryption through authorized software under the condition of establishi...
