Embodiment Construction

[0017] figure 1 A mixed form of a flow diagram and a functional diagram is shown, which illustrates the sequence of the method according to the invention for setting a predetermined state of an anti-theft device for a device. Wherein, the device can be, for example, a car, but generally speaking, the device can be any device, for example, it can also be a notebook computer or a mobile phone. In the following it is assumed that the device is a car as an example. The definition of an anti-theft device originated in the automotive field, and here it means a broad prevention of unauthorized use of any device. In this way, the device will be worthless for an unauthorized user, so the theft of this device is meaningless especially for an unauthorized user, and the occurrence of theft can be avoided.

[0018] In this example, the predetermined state is the initial state of the antitheft device. In general, any other state of the antitheft device can also be referred to. The initi...

Abstract

The method involves encrypting an identification code (1) of an immobilization lock using a private key (10) to obtain an encrypted identification code (20) that characterizes a predefined state of the lock. The encrypted identification code of the lock is decrypted to generate an identification code (5) with a public key. The predefined state of the lock is recognized in case of coincidence between the codes (1, 5). Independent claims are also included for the following: (A) an encrypting device to install an immobilization lock of a device (B) a device to recognize a predefined state of an immobilization lock.

Description

technical field [0001] The invention relates to a method for setting a predetermined state of an anti-theft device for a device, an encryption device for setting a predetermined state of an anti-theft device for a device and identification of an anti-theft device for a device according to the preambles of the independent claims Identification means for a given state of the device. Background technique [0002] It is known to set the so-called initial state to the predetermined state of the anti-theft device by writing a simple signature word into the non-volatile memory of the controller of an anti-theft device, eg EEPROM. But this method is not counterfeit-proof. Contents of the invention [0003] The method for setting the predetermined state of the anti-theft device for a device and the encryption device for setting the predetermined state of the anti-theft device for a device with the characteristics of independent claims 1 and 9 are as follows relative to the above-m...
