1. About the KOBRA Stick The KOBRA Stick is an encrypted USB-C stick in a sturdy, metal casing. It enables the storage, safekeeping and secure transport of sensitive business and private data for public authorities and companies in accordance with data protection regulations. It was developed in accordance with the “Technical Guidelines”...
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).
- Internal power supply that allows authentication without connecting to a PC or USB hub. Optional: - USB VID, PID & serial numbers can be defined according to customer specifications - Laser-engraved customer specific information on the back of the KOBRA Stick...
- Easy and secure handling due to hardware encryption: connect, login, use - All data is immediately stored as encrypted - No performance losses 2. USB port and input interface The KOBRA Stick can be connected to a PC via a USB port. USB-C 3.0 port...
(cancel) (confirm) On the front of the KOBRA Stick there is an input keyboard with a main key, two command keys (“×” cancel and “√” confirm) and ten input keys (0 to 9). Connection with a PC is via a USB-C 3.0 port.

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 goes into authentication mode both after pressing the main key for approx.
In menu mode, the main key lights up blue and all other input keys white. To execute the commands, the KOBRA Stick usually requires a connection to a PC or another external power supply (e.g. USB power supply or USB hub). Exceptions to this are during authentication on the KOBRA Stick, the activation or deactivation of the write protection as well as the generation of new crypto keys.
5.2 Changing the user PIN On the KOBRA Stick the user PIN is needed to carry out authentication (login), to activate write protection and to deactivate, destroy or generate encryption keys. In the KOBRA Stick factory settings the user PIN is “1- 2-3-4-5-6-7-8”. The stick will also have this PIN when the permitted number of failed attempts to login has been exceeded and the user PIN has been reset to the factory settings.
In the KOBRA Stick factory settings, the administrator PIN is “8-7-6-5-4- 3-2-1”. When entering the admin PIN, 16 failed attempts are allowed. If this number is exceeded, the admin PIN is irreversibly blocked and the above functions can no longer be changed.
4) Enter the user PIN and confirm with “√“. After the crypto key has been successfully generated or changed, the main key flashes green briefly and the KOBRA Stick switches back to wait mode. During the next authentication, the main key flashes blue until the formatting has been...
5.7 Time-out and quick-out functions The administrator can define after how many minutes the activated KOBRA Stick is automatically locked if neither reading nor writing access to the stick takes place within the specified time.
If the process was successful, the main key flashes green briefly and the KOBRA Stick switches back to the wait mode. The quick-out function allows you to log off quickly. It is executed by double-clicking the “×” key within 2 seconds 5.8 Permitted number of failed attempts for entering...
Extension programs can also be used to write data to file systems where this would not otherwise be possible. Of course, it is also possible to format the KOBRA Stick with any other file system. This does not affect the encryption of the data and the settings already made.
USB connection. The user PIN is not transmitted to the recipient until this information matches. This method enables the KOBRA Stick to deliver sensitive data to the recipient safely and cost-effectively using an insured parcel or courier service.
KOBRA Stick are generated anew and the user PIN is redefined. The number of permitted failed attempts can also be reduced for these purposes to the minimum values of, e.g. 1 to 3. The data can then be stored on the KOBRA Stick and sent by post or courier (see chapter 7.2).
The integrated autonomous power supply enables authentication of the KOBRA Stick to take place before a PC is started (pre-boot authentication). This feature allows operating systems to be stored in encrypted form on the KOBRA Stick and then started directly from the stick.
(e.g. USB power supply or USB hub). This feature of the data carrier is called pre-boot authentication (Chapter 3). The KOBRA Stick can also be used as a boot medium with an installed operating system. When the stick is connected to any PC, the operating system installed on the stick starts.
3D TLC, MLC and pSLC 9. Data security and disclaimer We recommend that you also regularly back up the data on the KOBRA Stick on other storage media. This will protect you from complete data loss.
