Abstract

Disclosed herein are systems, methods, and non-transitory computer-readable storage media for performing in-place encryption. A system configured to practice the method receives a request from a user to encrypt an unencrypted volume of a computing device and identifies, generates, and/or randomly selects a volume key. Then the system converts the unencrypted volume to an encryptable format divided into portions. The system then encrypts, based on the volume key, the encryptable volume, portion by portion, to enable the user to use the computing device while encrypting. The system can maintain an encryption progress status and display the encryption progress status. The system can monitor disk accesses to the encryptable volume, and, when the disk accesses exceed a first threshold, apply a back-off algorithm to stop encrypting until the disk accesses fall below a second threshold. Thus, the computing device can be used while the encryption occurs in the background.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Patent Application Serial No. 12 / 985,190, filed January 5, 2011, entitled "SYSTEM AND METHOD FOR IN-PLACE ENCRYPTION," which is incorporated by reference in its entirety, including here. technical field [0003] The present disclosure relates to encrypted storage, and more particularly to in-place encryption of storage within a computer while a user continues to use the computer. Background technique [0004] As the capacity and popularity of storage devices increase, many users and organizations are naturally concerned with protecting the stored data. Some of the threats that users may want to protect their data from include identity theft, corporate espionage, invasion of privacy, hacking, and more. Data stored on storage devices is vulnerable to theft of physical storage devices and unauthorized access via network-based attacks. Enterprises are usually concerned with the p...
