HAK2/bibi

hardware key for transmission encryption in the bibi.net system

Application

In the access control and time & attendance control programme - bibi.net - the USB hardware key has the following functions:

• Securing against usage of illegal programme copies - checks if the key is present while starting up the programme
• Securing access to the programme - loggin into the programme by checking user passwords in the HAK2 key
• Making particular programme functions accessible by generating digitally signed licences
• Encrypting data saved on the computer's disk
• Encrypting transmissions between computers in the same installations

ATTENTION
The HAK2/bibi hardware key must be inserted into a USB socket in each computer which is a bibinet network node. It is recommended to have one HAK2/bibi key more thant the number of nodes (number of nodes + 1). The additional key (the so called system key) is a model key for the whole installation and can be used to programme additional keys (for example when some of the keys are damaged, lost, or when the installation is being expanded).
EXCEPTION - in a single station installation (one node) with the programme licence (not bought seperately - sold along with devices) a USB code key is not required. It is being emulated in the computer's registers.

General description

The HAK2 key is designed as a plug inserted directly into a USB socket.

The HAK2 key uses the lowest USB speed for communication with the computer (Low Speed = 1,5Mb/s). Thanks to this the computer only needs to be equipped with the older USB 1.1 specification.

HAK2 does not need any specific driver installed in the system. It uses the standard HID (human interface device) driver, which is available in the Windows® system since the Windows®98 version. This driver is also available in any operating system which allows connecting a USB keyboard.

Data transmission between the programme and the HAK2 key is encrypted with the DES algorithm. For each session a different transmission key is created, which is based on the user's password and random numbers.
