System and method for general purpose encryption of data

摘要

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, and an encryption accelerator communicatively coupled to the processor. The encryption accelerator may be configured to encrypt and decrypt information in accordance with a plurality of cryptographic functions, receive a command from the processor to perform an encryption or decryption task upon data associated with an input/output operation, and in response to receiving the command, encrypt or decrypt the data associated with the input/output operation based on a particular one of the plurality of cryptographic functions.

1. An information handling system, comprising:
a processor; a memory communicatively coupled to the processor; a storage resource communicatively coupled to the processor; and an encryption status module stored in the memory and configured to:
determine an encryption status of a volume of the storage resource;track the encryption status of the volume by periodically storing, during an encryption or decryption task, a variable indicating a portion of the volume that has been encrypted or decrypted and whether the volume is at least partially encrypted or decrypted;determine whether the volume is in a partially encrypted or decrypted state in response to an interruption to the encryption or decryption of the data stored on the volume; andboot from the volume in the partially encrypted or decrypted state based on the determination that the volume is in the partially encrypted or decrypted state.
