Problems solved by technology

[0007] Microsoft provides some ways to back up the BitLocker recovery password to Active Directory, but manual operation of the administrator is required to obtain the password; and, when the end user needs to restore, there is no safe channel to submit the password to the end user, and this BitLocker recovery passwords have 48 digits, making it difficult for end users to recover from disaster situations, and while such recovery should be done with caution, it's still not a reliable way

[0051] In the first embodiment of the invention, the client is not a user of the domain.

[0052] like image 3 As shown, the BitLocker information backup step in the method for restoring BitLocker information in the Vista operating system in the first embodiment of the present invention specifically includes the following steps:

[0053] Step 301, the user starts the secure channel establishment module, and the secure channel establishment module establishes a secure channel between the client and the Services Server; where the secure channel is established as an HTTPS channel established after the terminal user is authenticated by biotechnology or other user information ;

[0054] Step 302, the secure channel establishment module downloads the BitLocker client application from the Services Server and sends it to the BitLocker client application module in the client computer;

[0055] Step 303, the BitLocker client application module interacts with Vista BitLocker to obtain...

[0069] In the first embodiment of the present invention, since the client computer is not a domain user, it does not have the ability to access the AD Server, so it is necessary to set up an ADAM equivalent to the AD Server to preserve the BitLocker information. In the second implementation of the present invention In the example, a case where the client is a domain user will be described in detail.

[0070] When the client is a domain user, the BitLocker information can be backed up to the AD Server by using the new features of the Vista operating system. For this part, please refer to http: / / technet.microsoft.com / en-us / windowsvista / aa906017. The content in Chapter 4.2.3 of aspx will not be repeated here.

Abstract

The invention discloses a BitLocker information recovery method and system in Vista Operation System, wherein, the method includes that, in normal condition, perform backup for the BitLocker information into a BitLocker information backup server in the safe mode; when terminal users request to acquire BitLocker information from the BitLocker information backup server, if only the terminal user certification is successfully passed, the BitLocker information backup server will use the safe mode to return the BitLocker information to the client machine. The method and system provided by the invention can perform pre-backup for the BitLocker information, so that, in case the BitLocker information is lost, the user can collect the BitLocker information from the BitLocker information backup server if only some measures are taken for the user's certification, so as to unlock the encrypted partition area. Since ID certification is performed for the user to take back the BitLocker information, and meanwhile, the BitLocker information is also transmitted in a safe mode, therefore, the mode is safe; meanwhile, the mode needs no participation of managers and provides uttermost convenience in use.

Description

technical field [0001] The invention relates to computer system security, in particular to a method for restoring BitLocker information in the Vista operating system. Background technique [0002] BitLocker drive encryption is a new security protection method applied to the Vista operating system, which can provide quite reliable protection for the offline data and operating system of the computer. [0003] BitLocker drive encryption can choose to use TPM (Trusted Platform Module, Trusted Platform Module) to provide stronger protection and ensure the integrity of the initial startup. BitLocker Drive Encryption helps prevent data from being stolen or viewed without authorization by encrypting the entire Windows volume. [0004] BitLocker Drive Encryption can also be used without a compatible TPM. Using BitLocker drive encryption in this way provides the ability to encrypt the entire volume, but cannot provide an additional layer of security for early boot file integrity ver...
