Kobra Stick VS VS is approved by the German Federal Information Security Authority (BSI) for government classified information up to NATO Restricted and EU Restricted.

The confidentiality of the data stored on the KOBRA Stick VS is protected against unauthorised access, for example if the data carrier is lost or stolen, or in the event of virtual or physical attacks.

As long as the KOBRA Stick VS is not connected to a PC or with an external power supply (e.g. USB power supply or USB hub) it stays in sleep mode and all keys are deactivated.

 The KOBRA Stick VS guarantees the confidentiality of data through the following security mechanisms:

  •  Encryption
  • Access control
  • Cryptographic key management
  • User management

Encryption

The encryption module integrated in the safety housing carries out a complete encryption of the KOBRA Stick VS. Every byte saved and each written sector on the storage device is encrypted in XTS mode, using two cryptographic keys according to the 256-Bit AES (Advanced Encryption Standard). The KOBRA Stick VS also encrypts temporary data and areas that are often ignored by encryption software.

User authentication

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 need to know the correct PIN
  • If the number of incorrect PIN entries is exceeded, the smart card is deactivated and can no longer be used
  • The cryptographic keys is also irreversibly deleted

Management of the cryptographic keys

The user can generate, change or destroy the cryptographic keys at any time. This process is irreversible. After the generation of new cryptographic keys, the old cryptographic keys and thus all data stored on the data carrier are irreversibly destroyed. Therefore, any information stored on the drive should first be saved on another encrypted data carrier, where necessary.

The two 256-bit encryption keys for the encryption and decryption of the data are generated by a hardware random number generator and stored within the drive. When the user PIN is entered correctly they are transmitted to the encryption module of the KOBRA Stick VS for the encryption and decryption of the data.

Smart cards

Kobra Stick VS comes standard with two Digittrade smart cards (Atos CardOS 5.3, CC EAL 4+) certified according to Common Criteria EAL4 +. In a stand-alone environment, only these smart cards are approved for use in accordance with the VS-NfD authorization.

In addition to DIGITTRADE smart cards, PKI-based business, service and unit identification cards can also be used for authentication. From the point of view of confidentiality, all data stored on the KOBRA Stick VS VS are protected against unauthorized access in the event of loss or theft.

These smart cards allow you to create, copy, change and delete used cryptographic keys. Key management is performed on the Kobra VS disk using a Smart Card Digittrade (or PKI) and a user PIN completely independent of the PC.
