Hard disk encryption equipment and encryption use method

Abstract

The invention relates to a hard disk encryption device and an encryption use method, the hard disk encryption device comprises an encrypted hard disk and a customized BIOS, the customized BIOS is used as software to be installed in a computer, the customized BIOS can check a user password on a BIOS input interface after the computer is started, the password is a power-on password set by a user in the BIOS, and the process does not need the participation of the encrypted hard disk; the encrypted hard disk is connected with the customized BIOS through a connecting port on a computer, so that data transmission between the encrypted hard disk and the customized BIOS is realized, two sets of keys are stored in the encrypted hard disk and the customized BIOS, one set is an external authentication key PIK, and the other set is a data encryption key DEK; the external authentication key PIK can perform comparison authentication on the identity of the encrypted hard disk and the identity of the customized BIOS; the data encryption key DEK can encrypt data in the encryption hard disk through a symmetric algorithm; the device has the advantages of being reasonable in design and high in safety.

Description

technical field [0001] The invention belongs to the technical field of hard disk encryption, and in particular relates to a hard disk encryption device and an encryption use method. Background technique [0002] With the rapid development of computers, the data storage security of storage devices has attracted more and more attention; network storage devices are facing the threat of network intrusion and stealing confidential information. Data encryption technology is an important means of information confidentiality to protect stored data from leakage For unauthorized users, it plays an important role in protecting personal private information, military, and commercial confidential information; most of the existing hard disk encryption methods use hard disk password locks, and users can set access to hard disks through BIOS options. Password, when the user starts the computer to access the hard disk every time, the BIOS needs to verify whether the password entered by the us...

[0002] With the rapid development of computers, more and more attention has been paid to the data storage security of storage devices; network storage devices are facing the threat of network intrusion and theft of confidential information. Data encryption technology is an important means of information confidentiality to protect stored data from leakage For unauthorized users, it plays an important role in protecting personal private information, military, and commercial confidential information; most of the existing hard disk encryption methods use hard disk password locks, and users can set access to hard disks through BIOS options. Password, when the user starts the computer to access the hard disk each time, the BIOS needs to verify whether the password entered by the user is the same as the access password, and authenticate the user's identity. However, when this method is used, it only restricts data access , the data itself is still not protected, and the hard disk password lock needs to enter the password every time you log in, and the operation is cumbersome; therefore, in order to solve the above problems, a hard disk encryption device with reasonable design and good security and encryption usage necessary
