Problems solved by technology

[0003] Since the password input software needs to be fully activated after the system disk can be run normally, that is, the password input software can only input the password after the system disk is fully activated, so that the system disk does not need and cannot be decrypted during startup.
Since the decryption process cannot be performed, it means that the system disk cannot be encrypted in advance. It can be seen that the password input software in the prior art cannot realize the data encryption and decryption process on the system disk, thus the data security in the system disk cannot be guaranteed.
[0004] In addition, because password input software is a kind of software, it is easy to be infected by computer viruses. At the same time, the password input program corresponding to the password input software also has the possibility of being decompiled. It can be seen that when data is encrypted in the prior art, Passwords are less secure

Abstract

The application discloses a BIOS encryption-based safety hard disk, and a data encryption and decryption method, and the safety hard disk is applied to a computer with BIOS, and comprises a first password receiving module, a second password receiving module, a key generation module, a key storage module, a data receiving module and a data storage module. In the application, a user password and a data reading password are input by the BIOS of the computer, which means that the user password and the data reading password are input before complete starting up of the system, so the aim of decrypting encrypted data in the safety hard disk before the complete starting up of the system is achieved. In this way, the safety hard disk can be used as a system disk for realizing data encryption and the data safety of the system disk is improved. Meanwhile, as the system is not completely started up, virus software cannot be operated, the condition that the passwords are infected and decompiled by virus is avoided and password safety is improved.

Description

technical field [0001] The invention relates to the technical field of data hard disks, in particular to a secure hard disk based on BIOS encryption, and a data encryption and decryption method. Background technique [0002] Currently, computers usually contain two types of hard disks, one is a system disk and the other is a data disk. When the data in the computer needs to be encrypted and decrypted, the data is usually encrypted and decrypted by using the password input by the password input software. [0003] Since the password input software needs to be fully activated after the system disk is fully activated, that is, the password input software needs to be fully activated after the system disk is fully activated, so that the system disk does not need and cannot be decrypted when it is activated. Since the decryption process cannot be performed, it also means that the system disk cannot be encrypted in advance. It can be seen that the password input software in the pri...
