Abstract
Systems and methods are disclosed for secure relocation of encrypted files for a system having non-volatile memory (“NVM”). A system can include an encryption module that is configured to use a temporary encryption seed (e.g., a randomly generated key and a corresponding initialization vector) to decrypt and encrypt data files in an NVM. These data files may have originally been encrypted with different encryption seeds. Using such an approach, data files can be securely relocated even if the system does not have access to the original encryption seeds. In addition, the temporary encryption seed allows the system to bypass a default key scheme.
