20140359302 | System and Method for Intercept of UEFI Block I/O Protocol Services for BIOS Based Hard Drive Encryption Support - An information handling system and method performs Unified Extensible Firmware Interface (UEFI) interception and pre-processing of data associated with block input/output (I/O) commands targeting encrypted storage devices. A UEFI interceptor block (IB) I/O driver intercepts each block I/O command targeting block addresses on a storage device and identifies whether any of the target block addresses is encrypted. In response to identifying an encrypted block address among the target block addresses, the UEFI IB I/O driver forwards data associated with the encrypted block address to an encryption-decryption module to perform one of an encryption and a decryption of the data. Final handling of the block I/O command is performed using a block I/O driver chained to the UEFI IB I/O driver. Data associated with I/O commands targeting encrypted block addresses is first processed by the encryption-decryption module before final handling of the I/O command is performed by the block I/O driver. | 12-04-2014 |
20150242630 | SYSTEMS AND METHODS FOR SECURING BIOS VARIABLES - In accordance with embodiments of the present disclosure, a method may include generating a master cryptographic key for encrypting and decrypting the one or more variables stored in a non-transitory computer-readable medium accessible to a basic input/output system of an information handling system. The method may also include encrypting the master cryptographic key with a system password, such that the master cryptographic key as encrypted with the system password may be decrypted and used to encrypt and decrypt the one or more variables in response to entry by a user of the system password. The method may further include encrypting the master cryptographic key with an administrator password, such that the master cryptographic key as encrypted with the administrator password may be decrypted and used to encrypt and decrypt the one or more variables in response to entry by an administrator of the administrator password. | 08-27-2015 |
20150277895 | Method for Generating Custom BIOS Setup Interface and System Therefor - Configuration options to be displayed at a basic input/output system (BIOS) setup interface of an information handling system are specified using a software application executed at the system.
