摘要：
A method is provided for providing an operating system (OS) independent input/output (I/O) filter driver capable of encrypting at least a portion of a logical unit (LUN), the method comprising the unordered steps of: providing an I/O filter driver component to an I/O stack for a host in communication with the LUN; determining, based at least in part on at least one of OS requirements and an arrangement of data on the LUN, at least one region in the LUN that contains data that is used below the I/O filter driver in an I/O stack on the host; and performing at least one of a read and a write of the one or more regions while keeping the one or more regions in plaintext, while permitting other regions of the LUN to be at least one of encrypted and decrypted.
