The DIGITTRADE HS256 S3 is delivered completely pre-set and is ready to use for data storage. In the BSI-certified configuration, the user is only allowed to use the hard drive, after he has changed the smart card PIN, the encryption key on the smart card has been generated by himself and the smart card has been initialized.

From the point of the stored data, the DIGITTRADE HS256 S3 is secure from unauthorized access even in the case if it will be lost, misplaced, or stolen as well as from digital and physical attacks.

Encryption

Every saved byte and every written sector on the hard drive SSD are encrypted according to 256 bit AES (Advanced Encryption Standard) in XTS mode with two 256 bit cryptographic keys.

User authentication

The user authentication is based on the principle “having and knowing”

  • To get access to the data the user must have a smart card and need to know the correct 8-digit PIN
  • If the 8-digit PIN was entered incorrectly 8 times, the smart card is disabled and no longer usable
  • The cryptographic keys is also irreversibly deleted

Management of the cryptographic keys

The cryptographic keys needed for de- and encrypting of the data are externally created and encrypted and then stored on the smart card separately from the hard drive. With the device PIN, the user can copy the cryptographic keys to another smart card, initialize new smart cards on the HS256 S3 and manage the lock-out mode.

In particular usage scenarios, the knowledge of the smart card PIN and the device PIN can be split between two people, with the intention that only one person knows the device PIN and the other one smart card PIN. Knowledge of device PIN only will not enable the individual access to the data.

Smart cards

Serially the HS256 S3 works with two java based and Common Criteria EAL5 certified smart cards (NXP J2E081_M64 R3, CC EAL 5). For the use, according to the BSI certification, only these NXP smart cards are permitted.

These smart cards enable the creating, copying, changing, and destroying of the cryptographic keys in use. Key management is performed independently of the computer supporting the DIGITTRADE HS256 S3 applet.

For the login on the hard drive are both smart cards are needed with the same cryptographic keys. The smart card PIN can be set differently for each smart card.

In the event of any tampering attempt, the cryptographic keys on the smart card will be destroyed and the smart card will be automatically irrevocably blocked. The data on the hard disk is retained and can be accessed and edited using a second smart card after entering the correct PIN.

Extra features

The 2.5-inch built-in data storage device makes the HS256 S3 small and handy. The optional usage of SSD storage devices makes it shockproof. The data transfer and power supply are solved by USB. The hardware encryption method makes it possible to use the storage device on any OS and occurs transparently. Accessing the data occurs without the loss of reading/writing speed.
