Method and device for encrypting hard disk partition

Abstract

The invention relates to the field of computers and discloses a method and device for encrypting a hard disk partition. The method and the device are used for preventing data leakage of a hard disk and increasing data safety of the hard disk. The method comprises the following steps: when a starting process of an operation system on a user terminal is triggered, after being subjected to USBKEY authentication, an encryption key can be guided into the operation system to be stored temporarily according to a pre-set safety transmission mechanism; after obtaining the encryption key, the user terminal takes an appointed hard disk partition as an encryption partition to mount; and read-write operation of the encryption partition is encrypted and decrypted according to the obtained encryption key, therefore, data dynamic read-write encryption and decryption are realized in a driving layer; by means of driving of an independent file system, hook hijacking of the original file system of the operation system by a third party is stopped, so that the data safety is effectively increased; furthermore, mounting of the encryption partition and seamless integration of the starting process of the operation system are realized, and the execution efficiency of a hard disk encryption process is increased.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method and device for encrypting hard disk partitions. Background technique [0002] With the increasing application of computer technology, how to ensure data security has become the most concerned issue for users. In order to ensure data security, encryption technology is usually used to encrypt various file data stored. [0003] Currently, commonly used encryption technologies mainly include file encryption technology and disk encryption technology. [0004] First of all, the file encryption technology will be introduced first. The so-called file encryption technology, whose core is to implement encryption control based on the application process, has the following advantages: [0005] 1. The deployment is simple, and there is no need to change the user's operating habits or the user's application environment; [0006] 2. The technology is simple, only involving process file ass...

AI Technical Summary

Problems solved by technology

[0012] However, because the disk encryption technology only protects specific file storage areas and lacks the ability to judge the confidentiality of the files themselves, it has the following disadvantages: the use of disk encryption technology requires conditional restrictions on the file storage area, so it is necessary to use environment adjusted to accommodate disk encryption

Furthermore, a single disk encryption technology cannot prevent file leaks through the network and other channels, and if it is necessary to integrate network control technology to develop corresponding network security products, the development is difficult and the cycle is long

On the other hand, there is no complete key management mechanism in the current disk encryption technology. Once the key is forgotten, there is no effective recovery method.
