## Abstract

A system and method for secure vehicle communication of a vehicle. The system comprises a communication system comprising at least one telematics module for executing one or more telematics applications, and a session module for session management of the telematics applications, wherein the session management comprises the assigning of at least one session identification, session ID, to each telematics application, wherein the session module assigns a new session ID to each telematics application after expiration of a predetermined time period.

## Claims

### Claim 1

A system for secure vehicle communication of a vehicle, comprising:
a communication system comprising:
at least one telematics module for executing one or more telematics applications,
a session module for session management of the telematics applications, wherein the session management comprises an assignment of at least one session ID to each telematics application;
wherein the session module assigns a new session ID to each telematics application after expiry of a predetermined period.

### Claim 2 (depends on 1)

The system according to claim 1, further comprising:
a storage module;
wherein the session module stores a correlation of all session IDs to the vehicle locally in the storage module.

### Claim 3 (depends on 2)

The system according to claim 2, wherein
the correlation of the session IDs to the vehicle in the storage module is periodically overwritten.

### Claim 4 (depends on 2)

The system according to claim 2, further comprising:
a control module, wherein the control module reads the correlation of the session IDs to the vehicle from the storage module in the case of a predeterminable event and transmits said correlation to a corresponding telematics service provider and/or a trusted backend server.

### Claim 5 (depends on 4)

The system according to claim 4, wherein
the predefinable event comprises a request to transmit the correlation of the session IDs to the vehicle via an input and output unit of the vehicle.

### Claim 6

A method for secure vehicle communication of a vehicle, comprising:
executing one or more telematics applications via at least one telematics module; and
carrying out session management of the telematics applications via a session module in the vehicle, wherein
the session management comprises an assignment of at least one session ID to each telematics application, and
the session module assigns a new session ID to each telematics application after expiry of a predetermined period.

### Claim 7 (depends on 6)

The method according to claim 6, further comprising:
storing a correlation of all session IDs to the vehicle in a local storage module,
wherein the correlation of the session IDs to the vehicle in the storage module is periodically overwritten.

### Claim 8 (depends on 7)

The method according to claim 7, further comprising:
transmitting the correlation of the session IDs to the vehicle to a corresponding telematics service provider and/or a trusted backend server in the case of a predeterminable event;
wherein the predeterminable event comprises a request to transmit the correlation of the session IDs to the vehicle via an input and output unit of the vehicle.
