Abstract

Electrical / electronic System, with at least one basic device, which wireless information or exchanges data with at least one partner device, where possible the encrypted information or data exchange between the two devices before at least one common Secret be exchanged in the form of an identification code must, characterized in that at least one basic unit (1) via a Generation device (4) for the random generation of an identification code (5) and about at least one output device (7, 8) for outputting the identification code (5), and that at least one partner device (2) has at least one input device (11, 12) for manually entering the randomly generated identification code (5).

Description

The The present invention is based on one according to the preamble of the main claim designed electrical / electronic system.

Mobile phones, Headsets, PDAs, PCs, PALMs, etc. are often as such electrical / electronic Networked systems. A radio connection is often used for information purposes. or data exchange used. In many cases, the radio connection designed as a so-called Bluetooth connection. To each other related devices of such an electrical / electronic system to protect against eavesdropping, are complex encryption methods State of the art. To match the devices to be connected often first manually an identifier in the form of a PIN in at least one of the devices be entered. Often are set for this purpose by default and simply constructed PINs, such. B. - 1234 - provided or enter or it is a PIN on at least one of the devices as removable Adhesive strips available. This embodiment, such well-known But electrical / electronic systems do not just lead to one considerably higher Risk regarding the privacy, because the PIN can be easily guessed or read, but is if done correctly with setting or entering a complex PIN accordingly cumbersome in handling.

outgoing from such a situation, the present invention is the The object of the invention is to switch an electrical / electronic system which with simple handling, even a complex PIN high level privacy guaranteed.

According to the invention this Problem solved by the features specified in the main claim.

at Such a design is particularly advantageous that through the Generating device, whenever necessary randomly a new identification identifier generated by the user under direct guidance help only in the partner device or in the partner devices must be entered manually for identification.

Further advantageous embodiments of the subject invention are specified in the subclaims. Based on a block diagram, the invention will be explained in more detail in principle. Showing:
the block diagram of an electrical / electronic system with a base unit and with a partner device.

As can be seen from the block diagram, the basic device 1 a generating device 4 which, for the random generation of an identification identifier 5 , z. B. - q32t2V - is provided. Via the activation key 6 If required, a new, complex identification identifier can be created at any time based on the randomness principle 5 be retrieved. Because the identification code 5 is generated randomly and is executed complex as a multi-digit string, the condition for a particularly high privacy is guaranteed. Optionally, the identification identifier 5 via a first output device designed as a screen or LC display 7 and / or via a second output device designed as a loudspeaker 8th visually displayed, or be emitted acoustically.

For identification, the user can 10 now in a simple way, the displayed and / or announced identification identifier 5 under direct guidance in the partner device 2 enter. This can be the user 10 either via the keypad first input device 11 or via the provided with a microphone speech recognition module of the second input device 12 accomplish. By pressing a send button 13 becomes the process of mutual authentication of the devices (pairing) with the help of the common identifier 5 initiated.

The user 10 Thus, in such a trained electrical / electronic system in a particularly simple and convenient way a tap-proof connection between a basic unit 1 or several basic devices and a partner device 2 or create multiple partner devices.

Claims (6)

Electrical / electronic system, with at least one base unit which wirelessly exchanges information or data with at least one partner device, to enable the encrypted information or data exchange between the two devices previously at least a common secret in the form of an identification identifier must be replaced characterized in that at least one basic unit ( 1 ) via a generating device ( 4 ) for the random generation of an identification code ( 5 ) and at least one output device ( 7 . 8th ) for issuing the identification code ( 5 ) and that at least one partner device ( 2 ) at least one input device ( 11 . 12 ) for manually entering the randomly generated identification code ( 5 ) on has.
