An audio input interface () receives a digital audio signal and identifies an audio bitstream which is optionally decrypted by a decryption unit (), and decoded by an audio decoding unit (). An audio digital to analog converter () converts the decoded audio bitstream to an analog audio signal which is optionally decrypted by an audio analog decryption unit () and output by an audio output interface () to an analog wireline device (). A video input interface () receives a digital video signal and identifies a video bitstream which is optionally decrypted by a video digital decryption unit (), and decoded by a video decoding unit (). A video digital to analog converter () converts the decoded video bitstream to an analog video signal that is optionally decrypted by a video analog decryption unit () and output by a video output interface () to the analog wireline device ().

A first vehicle obtains from a certification authority a certification that an authentic vehicle is associated with a cryptographic key. The certification certifies that the cryptographic key is bound to information identifying the authentic vehicle, and may be implemented. The first vehicle utilizes the cryptographic key obtained from the certification authority in cryptographic communication with a second vehicle, and determines whether the second vehicle is the authentic vehicle based on whether the cryptographic key is successfully utilized in the cryptographic communication. Upon determining the second vehicle is the authentic vehicle, the first vehicle may communicate further with the second vehicle.

Method and system for vehicle authentication of another vehicle

A vehicle authenticates a service technician and accesses a technician database to determine whether the service technician is indicated as authorized to perform the service operation. If the service technician is indicated as authorized to perform the service operation, the vehicle allows the service technician to perform the service operation.

Method and system for vehicle authorization of a service technician

A vehicle accesses a configuration database to determine whether a reconfiguration function is authorized. The reconfiguration function may involve, for example, installing the component in the vehicle, removing the component from the vehicle, replacing the component with another component in the vehicle, replacing another component in the vehicle with the component, modifying the component, upgrading the component and rendering the component operable. Upon determining that the reconfiguration function is authorized, the vehicle allows the reconfiguration function to be performed. The reconfiguration function may be authorized based on a type of the vehicle, a type of the component or a combination of configuration elements in a current configuration of the vehicle.

Method and system for authorizing reconfiguration of a vehicle

The service technician accesses the prospective vehicle and obtains from a certification authority a certification that an authentic vehicle is associated with a cryptographic key. The service technician utilizes the cryptographic key in cryptographic communication with the prospective vehicle via a secure device having limited accessibility but being accessible by the service technician. The service technician determines whether the prospective vehicle is the authentic vehicle based on whether the cryptographic key is successfully utilized in the cryptographic communication with the prospective vehicle.

A component for use in a prospective vehicle obtains from a certification authority a certification that an authentic vehicle is associated with a cryptographic key. The certification certifies that the cryptographic key is bound to information identifying the authentic vehicle. The component utilizes the cryptographic key obtained from the certification authority in cryptographic communication with the prospective vehicle, and determines whether the prospective vehicle is the authentic vehicle based on whether the cryptographic key is successfully utilized in the cryptographic communication. Upon determining the prospective vehicle is the authentic vehicle, the component may allow the prospective vehicle to operate the component.

A vehicle subassembly obtains a prospective component for use in the vehicle subassembly. The vehicle subassembly also obtains from a certification authority a certification that an authentic component is associated with a cryptographic key. The certification certifies that the cryptographic key is bound to information identifying the authentic component. The vehicle subassembly utilizes the cryptographic key obtained from the certification authority in cryptographic communication with the prospective component, and determines whether the prospective component is the authentic component based on whether the cryptographic key is successfully utilized in the cryptographic communication.

A vehicle maintains a record of configuration elements, such as components for use in the vehicle, of the configuration of the vehicle. The vehicle also maintains a history of configuration functions for each of the configuration elements. The history may include a type of each configuration function, such as installation of a configuration element into the vehicle, and may also include a record of corresponding times at which the configuration functions have occurred, which can be utilized to determine a configuration of the vehicle at a time of an event. Additionally or alternatively, the vehicle may maintain a service history of at least one service technician performing a service operation with respect to a corresponding one of the configuration elements. The service history may include a type of each service operation, and may also include a record of a corresponding time at which the service technician performed the service operation, which may be utilized to determine a service technician having most recently performed a service operation at a time of an event.

In-vehicle resources (wherein the resources each provide a common category of capacity to effect a processor effected activity) are leveraged by selecting the processor activity, selecting for at least one vehicle, a plurality of in-vehicle resources, and parsing facilitation of the processor effected activity by parsing the common category of capacity across the plurality of in-vehicle resources.

Method for leveraging in-vehicle resources

Substantive informational conflicts as between navigation information provided by an in-vehicle navigation unit ( ) and an in-vehicle roadside information service receiver ( ) are detected ( ). When detected, information from one source or the other is modified ( ). Such modification can include alteration and/or deletion of one information item or the other. The modification can alleviate the conflict and/or otherwise provide alternative information to a user of the vehicle to support journey goals.
