1. About the DIGITTRADE HIGH SECURITY HDD

The external DIGITTRADE HIGH SECURITY HS128 / HS256 (external encrypted HDD/SSD) is one of the safest solutions to save mobile data based on its security features.

In regards to the confidentiality of the data the DIGITTRADE HS128 / HS256 is secure from unauthorized access even if it were to be stolen, lost or misplaced and also from digital and physical attacks.

The DIGITTRADE HS128 / HS256 ensures the safety of the data through the following safety mechanisms:

• Encryption
• User authentication

1.1 Encryption

- 256 bit AES full disk hardware encryption in CBC mode

The encryption module inside the secure casing does a complete encryption of the hard drive/SSD. Every saved byte and every written sector on the hard drive/SSD are encrypted according to AES (Advanced Encryption Standard) in 128 bit / 256 bit CBC mode.

The DIGITTRADE HS128 / HS256 also encrypts temporary files and areas that are often missed by encryption software

graph TD

    A --> C["cipher text"]

1.2 User authentication

- 2 factor authentication using smart card and PIN

The user authentication is based on the principal „having and knowing“

To get an access to the data the user must have the smart card and must know the correct 8 digit PIN.

If the 8 digit PIN is entered incorrect 8 times the smart card is disabled and useless. The cryptographic key is also irreversibly deleted.

1.3 The smart card

Two Smartcard (Smartcard Atmel CryptoMemory AT88SC014C) are used. The card can securely save cryptographic keys.

There are two different types of smart cards optionally available.

For higher security requirements, the smartcard Oberthur Cosmo 64 v5.4, certified by FIPS 140-2 level 3.

On the other hand, for especially high security requirements, two java based smart cards, NXP P5CD081 J3A081 JCOP v2.4.1 R3 (BSI-DSZ-CC-0675-2011) are available. These smartcards are certified by the BSI (Federal Institute of Information Technology) with EAL5.

In case of any manipulation the smart card will be irrevocably destroyed and disabled.

1.4 Extra features

The 2.5 inch built-in data storage device makes the HS128 / HS256 small and handy. The optional usage of SSD storage devices makes it shock proof.

3. Getting started with the HS128 / HS256

The necessary power supply for the HS128 / HS256 is provided by USB or FireWire. An extra power supply is usually not needed. If the cable you are using does not provide enough power an optional DIGITTRADE power supply can be purchased.

After correctly connecting the HS128 / HS256 to the computer the Status-LED will shortly light up „ACTIVE“, „STATUS“ and „ERROR“ in turn.

After which your DIGITTRADE HS128 / HS256 is operational yet it still has to be unlocked. Have your smart card and smart card PIN ready.

Note: For security reasons only use original accessories with your DIGITTRADE HS128 / HS256.

3.1 Inserting the smart card

After the DIGITTRADE HS128 / HS256 is operational it has to be unlocked for use.

To accomplish this insert your smart card (paying attention to the direction of the arrow) in the Harddrive.

If a valid smart card is inserted the „STATUS“-LED will flash once. Followed by the number pad lighting up and ready for the input of your PIN.

If an invalid smart card is inserted the „ERROR“-LED illuminates.

3.2 Entering the smart card PIN

After starting up and identifying a valid smart card the display on the DIGITTRADE HS128 / HS256 illuminates and is ready for you to enter the PIN.

Now the 8-digit PIN can be entered.

The factory set PIN is:

1-2-3-4-5-6-7-8

Enter the PIN using the touch pad

Then confirm with „ENTER“.

Note: to guarantee the safety of your data it is very important to change the factory set PIN (Page 57). Change the smart card pin periodically. It is recommended to use different PINs for different cards.

After successful smart card PIN input, the cryptographic key is transferred to the encryption module. The DIGITTRADE HS128 / HS256 is recognised as a removable media device and the LEDs on the touch pad go out.

You can now access the storage device. The Smart card must stay in the DIGITTRADE HS128 / HS256 whilst in operation. If the smart card is removed from the slot then the storage device will be blocked (Lock-Out Mode).

If wanted this function can be deactivated, so that the smart card can be removed after starting up and unlocking the HS128 / HS256 it is then furthermore accessible. More information in chapter 4.2.

If a wrong PIN has been entered the „ERROR“-LED illuminates. Press the „ESC“ Button to re-enter your PIN.

Note: The smart card is automatically disabled and useless as soon as the 8-digit PIN has been incorrectly entered 8 times. The cryptographic key in the smart card is irreversibly deleted in the process.

3.3 Changing the smart card PIN

Follow these steps to change your smart card PIN:

1) Insert the Smart Card into DIGITTRADE HIGH SECURITY HDD (see page 37).
2) Press the "CHANGE PIN" button and afterwards the "1" button.

6) Input the new 8-digit PIN again and confirm with „ENTER“.

7) After the PIN has been successfully changed the „STATUS“-LED flashes three times and you will hear two beeps.

8) The smart card can now be removed.

If changing the PIN was unsuccessful, the „ERROR“-LED illuminates. Press the „ESC” button and begin at step 1. of changing the device PIN.

Note: The DIGITTRADE HS128 / HS256 only accepts 8-digit PIN. The PIN should be chosen at random. Do not use any Trivial-PIN like ascending or descending number patterns or personal oriented PIN.

4.2 Activating/deactivating of the lock-out mode (Device PIN needed)

In the activated Lock-Out Mode access to the data is instantly stopped if the smart card is removed.

The HS128 / HS256 is factory set with lock out mode active. The „STATUS“- LED illuminates red during the authentication process.

The user can deactivate this feature in particular situations. This must be done when only one smart card has access to many different storage devices that are supposed to be unlocked at the same time but have the same cryptographic key. When the lock-out mode is deactivated the „STATUS“-LED illuminates green during the authentication process.

Follow these steps to activate/deactivate the Lock-out mode:

1) Insert the smart card into the DIGITTRADE HS128 / HS256. Paying attention that the „STATUS“-LED flashes once.

Note: After deleting the partition all data on the partition is irreversibly deleted.

- To generate a new partition on the unallocated space of the storage device click on „create”.

• Choose on which storage device you would like to create a partition.
• During the next step you will be asked which type of partition should be used. In most cases it is recommended to choose „primary partition“.

• In this window the settings are chosen. You can choose a file system, the size and even if needed the mount point in your system.
• When finished confirm your entries with „OK“.

- Formatting is similar, to do this choose the partition you would like to format and click on „Edit“.

- Lastly tick „format“ and choose a file system. Confirm with „OK“.

- In a new window all changes will be displayed. Make sure all settings are correct and confirm them by clicking „Finish”.

Note: If you are unsure about the file system and the size of the partition, it is recommended to use the already entered standard settings.

8. The Correct File System

- The table below shows the compatibility between operating systems and file systems.

	NTFS F	AT32 H	FS+ EXT	3
Win 98 X R, W X X
Win NT, 2000, ME, XP, Vista	R, W R	W X X
Mac OS X	R R, W	R, W X
Linux	R R, W	X R, W

R - read

W - write

X - no compatibility

You may be able to write data to file systems that are usually not compatible by using an external program.

The DIGITTRADE HS128 / HS256 is at the time of delivery already formatted for you in the NTFS file system. In the chart above you can see the compatibility of the NTFS file system with your operating system. If NTFS does not work with your operating system, you will have to re-format the hard drive (Chapter 6).

For Windows users we recommend NTFS. The most powerful file system for MAC OS X is HFS+ and for Linux you should use EXT3. The DIGIT-TRADE HS128 / HS256 can be formatted to any other file system, this does not affect the encryption of the data.

If you would like to use the hard drive with different operating systems, we suggest using the FAT32 file system, as it is supported by nearly all operating systems (Read/Write) However, there are restrictions to the file/partition size. Furthermore there are slight performance differences.

9. Possible usage of the DIGITTRADE HS128/HS256

1) Secure and cost-efficient data transport

The HS128 / HS256 can be used to transport confidential data. For this both the dispatcher and recipient of the data have a smart card with an identical cryptographic key. The dispatcher only sends the HS128 / HS256. As the cryptographic key does not physically exist (it is on the smart cards), it cannot be read out during transport. Additionally the HS128 / HS256 with confidential data can be sent cost-efficiently and insured by a postal service or courier.

The dispatcher and recipient must check that the HS128 / HS256 has not been tampered with during transport. Pay special attention to the DIGITTRADE security seals. You can also take other security measures like a sealed packaging. This is also effective for all other transport possibilities of the HS128 / HS256.

For additional security, the use of multiple smart cards with different cryptographic keys, (deposited at the dispatcher and recipient) which can be used to decrypt or encrypt the data in a chosen sequence.

Both of the branch offices have one or more smart cards with their own cryptographic key:

graph TD
    A["branch office 1"] --> B["TRANSPORT"]
    C["branch office 2"] --> B
    B --> D["Output"]

2) Data storage device & Authentication separation

Access to the data can be regulated so that it is only possible by i.e. combining three people. Person X has the HS128 / HS256, Person Y has the smart card and person Z knows the smart card PIN. The three people only meet for the data transfer at the recipient and separate again afterwards. Persons X,Y and Z cannot gain access to the data on their own.

graph TD
    A["person X has the device and transports the data"] --> D["Data transfer to the customer"]
    B["person Y has the smart card"] --> D
    C["person Z knows 8-digit PIN"] --> E["1.2-3.4-5-6-7.8"]
    D --> F["person X transports the HS256S to the data recipient"]
    E --> G["person Y and Z go to the next customer"]
    F --> H["data recipient has the smart card and PIN"]
    G --> H
    H --> I["Data transmission / data processing"]
    I --> J["pin"]

3) Deleting the cryptographic key

The cryptographic key can be deleted by incorrectly entering the 8-digit PIN 8 times.

7) Bootability

Operating systems, programs and data can be saved to the HS128 / HS256. This usage is compatible with stationary as well as mobile computers. By disconnecting the HS128 / HS256 from the pc, the data, programs and operating systems are saved and encrypted exclusively on the HS128 / HS256 and are inaccessible by unauthorized persons.

8) Usage with all operating systems

The HS128 / HS256 hardware encryption is standalone, which means it can be used on any device that supports data storage devices.

9) Integrating in existing software solutions

All existing software solutions can still be used to additionally expand the security properties and methods of use.
