Portable Digitrade HS256 Secure External Hard Drive

Brand New with 3 Year Warranty

750GB CAPACITY Portable Digitrade HS256 External Hard Drive The portable DIGITTRADE HIGH SECURITY HDD is currently the best solution to save data at a high standard of security and mobility.

Incl. Acronis TrueImage OEM Quick Backup Software

Thanks to the full disk hardware encryption according to the 256 bit AES in CBC mode and the two-factor authentication, by smartcard and 8-digit PIN, the DIGITTRADE HIGH SECURITY HDD combines the benefits of mobile data media with highest security standards for data privacy.

The encrypted HDD offers with its features in combination with the HS Smartcard Management System a lot of solutions for single users, companies and public authorities.

Besides, you receive with the Acronis True Image OEM Quick Backup software all necessary extras which you need for the restoration of a computer system in the disaster case. If mistakes appear which block access to information or influence the operating system, you can simply restore the system and lost data. Authentication The DIGITTRADE HIGH SECURITY HDD works with a two factor identification principleaccording to the having and knowing rationale:

Factor 1 (Having): verifies, if the user has a smartcard with the correct AES key.

Factor 2 (Knowing): verifies, if the user knows the correct 8-digit PIN and consequently is authorized to use this smartcard.

Only after successful authentication of the AES key used for encryption will information be transferred to the encryption chip set and the user will have access to the data.

1. Encryption During transfer on the HDD, all data is stored in real-time by a 256 bit full disk encryption according to AES in CBC mode.

The Advanced Encryption Standard (AES) is a symmetrical cryptographic system, approved by USA’s National Security Agency for top secret information.

ECB mode encrypts all sectors with a specified AES key.

The ECB Additionally to all stored data, even temporary files as well as areas that would normally not be noticed by encryption software will be encrypted. 2. Smartcard Serially the HDD is delivered with the smartcard Atmel CryptoMemory AT88SC0104C.

This offers enough security in everyday life. For especially high security requirements the smartcard Oberthur Cosmo 64 v5.4 is optionally provided, certified by FIPS 140-2 level 3.

These smartcards can be used either exclusively or in combination with the Atmel smartcards. In case of any manipulation the smartcard will be irrevocably destroyed and disabled. 3. AES Key The AES key is stored in the smartcard and cannot be read out from enclosure or HDD in case of loss or theft.

The construction of the HDD allows changing the AES keys as often as desired. For this purpose the new smartcards must be created with the adequate match key of the enclosure.

New data will be saved with the new AES key after the quick formatting of the HDD. The access to old data will be only limited possible by data recovery and using the old AES key. 4. HS Smartcard Management System The HS Smartcard Management System (HS SMS) is optionally provided. It allows:

• to generate AES keys
• to write new AES keys on new smartcards
• to manage smartcards, AES keys and users
• to write existing AES keys on a new smartcard
5. Supported Operating Systems The HDDs are bootable and are independent of any operating system.

This allows the users not only to store files and programs on the HDD, but also programs and complete operating systems.
