4.2.4 Encrypted File System

You can manage the encrypted disk volumes on the NAS on this page. Each encrypted

disk volume is locked by a particular key. The encrypted volume can be unlocked by the

following methods:

Encryption Password: Enter the encryption password to unlock the disk volume. The

default password is "admin". The password must be 8-16 characters long. Symbols

(! @ # $ % ^ & * ( )_+ = ?) are supported.

Encryption Key File: Upload the encryption file to the NAS to unlock the disk

volume. The key can be downloaded from "Encryption Key Management" page after

the disk volume has been unlocked successfully.

The data encryption functions may not be available in accordance to the legislative

restrictions of some countries.

Data Encryption on QNAP Turbo NAS

The disk volumes on the NAS can be encrypted with 256-bit AES encryption for data

breach protection. The encrypted disk volumes can only be mounted for normal read/

write access with the authorized password. The encryption feature protects the

confidential data from unauthorized access even if the hard drives or the entire NAS

were stolen.

About AES encryption:

In cryptography, the Advanced Encryption Standard (AES) is an encryption standard

adopted by the U.S. government. The standard comprises three block ciphers, AES-128,

AES-192 and AES-256 […]. Each AES cipher has a 128-bit block size, with key sizes of

128, 192 and 256 bits, respectively. The AES ciphers have been analyzed extensively

and are now used worldwide. (Source: http://en.wikipedia.org/wiki/

Advanced_Encryption_Standard)

The AES volume-based encryption is applicable only to specific QNAP NAS models.
