HS256S high security external hard drive

Professional solution for authorities and companies

"The HS256S external hard drive was awarded the Schleswig-Holstein and European data protection quality seal EuroPriSe in a combined process. Strong encryption technology and two-factor authentication implement privacy by design in an exemplary way and protect the confidentiality and integrity of the personal data stored on the hard drive."

(Translation of the Press Release from www.datenschutzzentrum.de) 

The HS256S portable high security hard disk enables data protection compliant storage, transmission and archiving of sensitive and personal data at authorities and companies.

The elegant 2.5 inch plastic housing protects against mechanical influences. The combination of FireWire 400 (800) and USB 2.0 ports ensures fast data transfer for reading and writing.

The HS256S is the first external hard drive to be awarded the ULD Privacy Seal and European Privacy Seal. By using this hard drive you meet the strictest requirements of the Federal Data Protection Act (BDSG) and the European Data Protection Regulation (EU-DSGVO) with regard to the secure storage of personal data.

The data stored on the HS256S is protected from unauthorized access, for example, if that hard drive is lost or stolen, as well as in the case of logical or physical attacks, with regard to the confidentiality of the information.

The Digittrade HS256S ensures the confidentiality of the data through the following security mechanisms:

• Encryption
• Access control
• Management of cryptographic keys

Security mechanisms and special features:

Encryption

The encryption module integrated in the security housing performs a complete encryption of the hard disk

Each stored byte and sector on the disk is encrypted to 256-bit AES (Advanced Encryption Standard) in CBC mode.

It also encrypts all temporary files and areas that are often overlooked by encryption software.

Access control

Access control is based on the principle of "Having and knowing": the user must have a suitable smart card and the correct PIN to access the data.

The smart card is automatically locked and unusable as soon as the 8-digit PIN has been entered incorrectly eight times. The cryptographic keys on the smart card are irrevocably destroyed. The data on the hard disk will continue to be stored securely. The access to this data can then be done with the second smartcard and the valid PIN.

Encryption key

The user can use the crypto keys themselves:

• Generate
• Change
• Copy
• Destroy

Management of cryptographic keys

The 256-bit crypto key is generated on the smart card. For this, the certified chip card has a very intelligent DRG3 random number generator.

Subsequently, this key is stored on the smart card separately from the hard disk and transferred only for encryption or decryption of the data to the crypto module of the hard disk.

The user can copy this key to the other smart cards and destroy it if necessary.

Smartcards

The storage device is supplied with two Java-based NXP J3D081 JCOP v2.4.2 R2 EAL5 smart cards as standard. They are certified to EAL5 by the German Federal Office for Information Security (BSI) and enable the cryptographic key to be created, copied, modified and destroyed. Key management is carried out on the smartcard independently of the PC with the support of the DIGITTRADE HS256S applet.

In the event of tampering attempts of any kind, the cryptographic key on the smartcard is destroyed and the smartcard is automatically and irrevocably deleted. The data on the storage device is saved and can be retrieved and edited using the second smartcard after entering the correct PIN.

Management software Smartcard Manager 2

The DIGITTRADE Smartcard Manager 2 is available separately and gives you a centralized view of all your DIGITTRADE High Security hard drives, smart cards and cryptographic keys. With this comprehensive management software, you can completely capture these high security hard drives. By displaying a company structure, employees, departments and locations can be assigned to the respective information. This allows you to add the hard disks and smart cards to the respective employees and departments. Already existing information can be updated.

You also have the possibility to manage your smartcards directly on your PC. The smart cards can be synchronized, cryptographic keys can be newly created, changed and deleted, and the smart card PIN can be changed.

Built-in hard disk

The built-in SATA hard drive in 2.5 "format makes the mobile data safe small and handy. The data transfer and the power supply via USB as well as the hardware encryption allow the use of the storage medium independently of the operating system.

Supported Operating Systems

The hard disks are independent of operating systems and bootable. This allows not only to store data but also operating systems and programs on these hard disks. This allows the HS256S to be used on all devices with USB support
