摘要： Systems and methods for reducing problems and disadvantages associated with traditional approaches to encryption and decryption of data are provided. A method for encryption and decryption of data, may include encrypting or decrypting data associated with an input/output operation based on at least one of an encryption key and a cryptographic function, wherein at least one of the encryption key and the cryptographic function are selected based on one or more characteristics associated with the data to be encrypted or decrypted. Another method may include encrypting an item of data based on at least one of a first-layer encryption key and a first-layer cryptographic function to produce first-layer encrypted data and encrypting the first-layer encrypted data based on at least one of a second-layer encryption key and a second-layer cryptographic function to produce second-layer encrypted 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 a computer-readable medium communicatively coupled to the processor. The computer-readable medium may have instructions stored thereon, the instructions configured to, when executed by the processor: (i) periodically store, during an encryption or decryption operation performed on the computer-readable medium, one or more variables indicative of an encryption status of a volume of the computer-readable medium; (ii) determine, based on the one or more variables, whether the volume is in a partially encrypted or decrypted state; and (iii) in response to a determination that the volume is in a partially encrypted or decrypted state, boot from the volume and continue the encryption or decryption operation.
