Connection key distribution

摘要

A system and a method implementing the method pertaining to securely providing a mobile device with a cryptographic key in a vehicle. The method includes generating a cryptographic key pair. The key pair may include at least a first cryptographic key and a second cryptographic key. The method may further include creating a label using a scannable image readable by a mobile device; the scannable image may be based on the second cryptographic key. And the method may include providing the label to the vehicle for displaying the scannable image.

1. A method of secure communication between a vehicle and a mobile device, comprising the steps of:
generating a cryptographic key pair comprising at least a first cryptographic key and a second cryptographic key; providing the first cryptographic key to a vehicle telematics unit (VTU); providing within the vehicle a scannable image associated with the second cryptographic key, wherein the scannable image is readable by the mobile device using a software application installed on the mobile device; receiving a message from the mobile device that is signed using the second cryptographic key after the mobile device has scanned the scannable image and extracted the second key; and deciphering the message using the first cryptographic key.
