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.

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.

The cryptographic keys is also irreversibly deleted.

If the 8-digit PIN was entered incorrectly 8 times, the smart card is disabled and no longer usable.

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

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

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.įrom 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.

The DIGITTRADE HS256 S3 is delivered completely pre-set and is ready to use for data storage.
