DATA PRIORITIZATION, STORAGE AND PROTECTION IN A VEHICULAR COMMUNICATION SYSTEM
First Claim
1. A device for use in a vehicular communication system, comprising:
- a communication module to at least receive vehicular data from a vehicular control architecture (VCA) in a vehicle in which the device is situated, and to receive intelligent transportation system (ITS) data from an on-board unit (OBU) also situated in the vehicle;
a key storage module to store at least one key for at least one of data encryption, data decryption or data signing;
a crypto module to utilize the at least one key for at least one of data encryption, data decryption or data signing; and
a secure storage module to store encrypted vehicular data received from the VCA and encrypted ITS data received from the OBU via the communication module, the vehicular and ITS data being encrypted by the crypto module utilizing the at least one key stored in the key storage module;
wherein the OBU;
is to interact with at least one of a road side unit (RSU) in the ITS or another vehicle, the interaction including at least one of receiving messages from, or transmitting messages to, the at least one of the RSU or other vehicle; and
is to interact with the at least one of the RSU or other vehicle on at least two channels, at least one of the at least two channels being reserved for high priority messages.

Abstract
This disclosure is directed to data prioritization, storage and protection in a vehicular communication system. A black box (BB) in a vehicle may receive data from an on-board unit (OBU) and a vehicular control architecture (VCA). The OBU may interact with at least one RSU that is part of an intelligent transportation system (ITS) via at least two channels, at least one of the at least two channels being reserved for high priority messages. The OBU may transmit ITS data to the BB via a secure communication channel, which may be stored along with vehicular data received from the VCA in encrypted form. In response to a request for data, the BB may authenticate a requesting party, determine at least part of the stored data to which the authenticated party is allowed and sign the at least part of the stored data before providing it to the authenticated party.

12. A method for protecting data in a vehicular communication system, comprising:
-
receiving vehicular data in a device from a vehicular control architecture (VCA) in a vehicle in which the device is situated; receiving intelligent transportation system (ITS) data from an on-board unit (OBU) also situated in the vehicle; storing at least one key for at least one of data encryption, data decryption or data signing; encrypting the vehicular data received from the VCA and the ITS data received from the OBU utilizing the at least one key; storing the encrypted vehicular and ITS data; and interacting with at least one of a road side unit (RSU) in the ITS or another vehicle, the interaction including at least one of receiving messages from, or transmitting messages to, the at least one of the RSU or other vehicle; wherein the OBU interacts with the at least one of the RSU or other vehicle on at least two channels, at least one of the at least two channels being reserved for high priority messages. - View Dependent Claims (14, 16, 17, 18)

19. At least one machine-readable storage medium having stored thereon, individually or in combination, instructions that when executed by one or more processors result in the following operations for protecting data in a vehicular communication system comprising:
-
receiving vehicular data in a device from a vehicular control architecture (VCA) in a vehicle in which the device is situated; receiving intelligent transportation system (ITS) data from an on-board unit (OBU) also situated in the vehicle; storing at least one key for at least one of data encryption, data decryption or data signing; encrypting at least one of the vehicular data received from the VCA or the ITS data received from the OBU utilizing the at least one key; storing the encrypted vehicular data and encrypted ITS data; and interacting with at least one of a road side unit (RSU) in the ITS or another vehicle, the interaction including at least one of receiving messages from, or transmitting messages to, the at least one of the RSU or other vehicle; wherein the OBU interacts with the at least one of the RSU or other vehicle on at least two channels, at least one of the at least two channels being reserved for priority messages. - View Dependent Claims (21, 23, 24, 25)
