High-Security encrypted USB flash drive KOBRA - Capacity: USB KSB - 32GB

It was developed in accordance with the “Technical Guidelines” of the BSI, has the quality marque “IT Security made in Germany” and, due to its security functions, is a good option for securely storing data on the move.

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

• Encryption
• Access control
• Cryptographic key management

Encryption

The encryption module integrated in the safety housing carries out a complete encryption of the KOBRA Stick. 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 also encrypts temporary data and areas that are often ignored by encryption software.

Access control

• Access is granted by entering a user PIN

The KOBRA Stick automatically creates a new encryption key and resets the user PIN to the default setting as soon as the permitted number of incorrect PIN entries has been exceeded. Access to the data stored on the drive is then no longer possible.

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 for the encryption and decryption of the data.
