Method and device for secure communication of a component of a vehicle with an external communication partner via a wireless communication link
First Claim
1. A method for secure communication of at least one of multiple components of a vehicle with at least one external communication partner, wherein the secure communication is via a wireless communication link and each of the multiple components includes at least one communication module for data exchange, comprising:
- exchanging data packets between a transceiver device of the vehicle and an external transceiver station;
ascertaining a communication status of the wireless communication link, wherein the communication status includes a level of security of the communication;
assigning a security level to individual components of the multiple components; and
as a function of the ascertained communication status of the wireless communication link, and the security level assigned to the individual components of the multiple components, at least one of;
(a) enabling at least one of;
(i) data exchange between the at least one of the multiple components and others of the multiple components,(ii) data exchange between the external communication partner and the others of the multiple components,(iii) access of the at least one of the multiple components to the others of the multiple components, and(iv) access of the external communication partner to the others of the multiple components; and
(b) disabling at least one of;
(i) data exchange between the at least one of the multiple components and the others of the multiple components,(ii) data exchange between the external communication partner and the others of the multiple components,(iii) access of the at least one of the multiple components to the others of the multiple components, and(iv) access of the external communication partner to the others of the multiple components.

Abstract
A method, a device, and a communication system are provided for secure communication of at least one of multiple components of a vehicle with at least one external communication partner via a wireless communication link, the multiple components in each case including at least one communication module for data exchange. The method includes exchange of data packets between a transceiver device of the vehicle and an external transceiver station, a communication status of the wireless communication link being ascertained and a data exchange between the at least one component and/or the external communication partner on the one hand, and the others of the multiple components on the other hand and/or an access of the at least one component and/or of the external communication partner to the others of the multiple components being enabled or disabled as a function of the communication status. The device and the communication system are provided for implementing the method.
