Dispositif de sûreté contre le vol utilisant un codage électronique d'autorisation d'utilisation pour véhicule. |
摘要 |
The invention provides a vehicle security device with an electronic use-authorization coding arrangement for preventing unauthorized access to the vehicle. The vehicle security device utilizes digital signature algorithm for encrypting and transmitting authorization and synchronization information, so that the storage of secret information is essential only at the key unit in order to transmit authorization and/or synchronizing information from the key unit to the vehicle unit in a way which is very effectively protected against falsification. Thus, reading out vehicle unit information does not permit unauthorized manufacture of a copied key. |
