Abstract
Systems and methods for reducing problems and disadvantages associated with traditional approaches to encryption and decryption of data are provided. An information handling system may include a processor, a memory communicatively coupled to the processor, an encryption accelerator communicatively coupled to the processor, and a computer-readable medium communicatively coupled to the processor. The encryption accelerator may be configured to encrypt or decrypt data in response to a command from the processor to perform an encryption or decryption task upon data associated with an input/output operation. The computer-readable medium may have instructions stored thereon, the instructions configured to, when executed by the processor: (i) monitor for input/output operations occurring prior to loading of an operating system into the memory; and (ii) in response to detection of an input/output operation, communicate a command to the encryption accelerator to perform an encryption or decryption task upon data associated with an input/output operation.
