Abstract: Replay attacks in an encrypted file system are prevented by generating a session key and providing the session key to one or more drive managers and an encrypted file system process. When a drive request is received by the encrypted file system process the drive request is encrypted using the generated session key. The encrypted drive request is sent to a drive manager. The drive manager attempts to decrypt the drive request using the session key. If the encrypted drive request is successfully decrypted, then the drive manager performs the requested operation. On the other hand, if the request is not decrypted successfully, then the request is not performed by the drive manager. Drive managers can include both disk device drivers and a logical volume managers.
