Ho w to us e the d ata e ncry ption fe a tu r e o n QNA P T urb o 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.
A bout A ES e ncry ption:
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.

Be fo r e y ou sta rt
Please beware of the following before using the data encryption feature of the NAS.
The encryption feature of the NAS is volume-based. A volume can be a single disk, a JBOD
configuration, or a RAID array.
Select whether or not to encrypt a disk volume before it is created on the NAS. In other words, you
will not be able to encrypt a volume after it has been created unless the disk volume is initialized.
Note that initializing a disk volume will clear all the disk data.
The encryption on the disk volume cannot be removed without initialization. To remove the
encryption on the disk volume, you have to initialize the disk volume and all the data will be
cleared.
Keep the encryption password or key safe. If you forgot the password or lost the encryption key,
the data cannot be accessed anymore.
Before you start, read the instructions carefully and strictly adhere to the instructions.
