Embodiment 1

[0041] see figure 1 , figure 1 It is a kind of implementation flowchart of BIOS hard disk password retrieval method in the embodiment of the present invention, and this method can comprise the following steps:

[0042] S101: Receive a BIOS hard disk password retrieval request.

[0043] When the hard disk needs to be accessed, if the access terminal currently forgets the password, a BIOS hard disk password retrieval request is generated, and the BIOS hard disk password retrieval request is sent to the hard disk password retrieval center. The hard disk password retrieval center receives the BIOS hard disk password retrieval request.

[0044] S102: Obtain a target secret key corresponding to the target public key that encrypts and stores the BIOS hard disk password.

[0045] Preset the public-private key pair consisting of the target public key and the target secret key. When the user sets the hard disk password in the BIOS setup interface (setup), the BIOS hard disk password ...

Embodiment 2

[0051] see figure 2 , figure 2 Another implementation flowchart of the BIOS hard disk password retrieval method in the embodiment of the present invention, the method may include the following steps:

[0052] S201: Receive a BIOS hard disk password retrieval request.

[0053] S202: Send permission verification information to the target internal server, so that the target internal server performs permission verification according to the permission verification information.

[0054] When receiving the BIOS hard disk password retrieval request, send authority verification information to the target internal server, and the target internal server performs authority verification according to the authority verification information. The authority of the key acquirer is verified by the target internal server, and formal decryption authorization authentication is performed, thus ensuring the legality of the current key acquisition behavior. For example, the identity information of ...

Abstract

The invention discloses a BIOS hard disk password retrieving method. The method comprises the following steps: receiving a BIOS hard disk password retrieving request; obtaining a target secret key corresponding to a target public key for encrypting and storing the BIOS hard disk password; and decrypting a pre-stored ciphertext BIOS hard disk password by using the target secret key to obtain a plaintext BIOS hard disk password, so as to decrypt the BIOS hard disk by using the plaintext BIOS hard disk password. By applying the BIOS hard disk password retrieving method provided by the invention, the quick retrieving of the hard disk password is realized, and the timely obtaining of important data of a user is ensured. The invention further discloses a BIOS hard disk password retrieving device and equipment, and a storage medium. The corresponding technical effects are achieved.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a BIOS hard disk password retrieving method, device, equipment and computer-readable storage medium. Background technique [0002] For user data security, the hard disk storage device can be encrypted in the basic input output system (BIOS, Basic Input Output System) of the server at present. The user enters the BIOS Setup interface, selects the security setting option, clicks hard disk password setting, enters the master password and user password, saves and restarts, and the hard disk password is set. After that, every time the server is turned on, the user will be reminded to enter the hard disk password. Only when the password is entered correctly can the hard disk boot system be entered. If the password is entered incorrectly, it will not be able to continue to boot, and if it exceeds a certain number of times, the hard disk will be locked to prevent brute force cracking. ...
