A device, a computer program, and a machine-readable memory medium, are also described.

Methods and devices are provided for uploading driving data to a blockchain network. The method is executed at a vehicle node in the blockchain network and includes: packing driving data of the vehicle node within a predetermined time interval every predetermined time interval to obtain a vehicle data packet of the vehicle, and storing the vehicle data packet locally in the vehicle node; broadcasting the vehicle data packet to other vehicle nodes located nearby and in the blockchain network for the other vehicle nodes to receive and store; receiving and storing other vehicle data packets broadcast by the other vehicle nodes located nearby and in the blockchain network; and when connecting to a fixed node that belongs to the blockchain network, synchronizing the vehicle data packet and the other vehicle data packets as stored to the fixed node, wherein the fixed node participates in the consensus of the blockchain network.

A vehicle data processing method and device are provided. The vehicle data processing method includes: acquiring vehicle data; determining a degree of completion of a preset goal according to the vehicle data; and determining incentive reference data associated with an incentive to a user according to the degree of completion of the preset goal.

Methods, apparatus, and systems for session key generation for AV operation are disclosed. In an embodiment, a vehicle service subscriber system generates an entropy. The vehicle service subscriber system is associated with a vehicle service subscriber. The vehicle service subscriber system transmits a synchronization message to a vehicle service provider system associated with at least one vehicle. The synchronization message includes the entropy. The vehicle service subscriber system receives a salt from the vehicle service provider system. The vehicle service subscriber system verifies that the salt was generated using the entropy. The vehicle service subscriber system calculates session keys using the salt. The vehicle service subscriber system receives a protected message from the vehicle service provider system. The vehicle service subscriber system authenticates the protected message using the session keys. The protected message is used to provide a ride involving the at least one vehicle.

Methods, systems and apparatus for session key calculation for autonomous vehicle operation are disclosed. A vehicle service provider system broadcasts a first salt to at least one vehicle service subscriber system. The vehicle service provider system is associated with at least one vehicle. The vehicle service provider system receives a synchronization message from the at least one vehicle service subscriber system. The synchronization message includes an entropy. The vehicle service provider system generates a second salt based on the first salt and the entropy. The vehicle service provider system calculates session keys based on the second salt. The vehicle service provider system sends an update to the at least one vehicle service subscriber system. The update includes the second salt for decrypting protected messages using the session keys. The protected messages are used to provide a ride involving the at least one vehicle. Other embodiments may be described or claimed.

Enclosed are embodiments for authenticating point cloud data. In an embodiment, a method of authenticating point cloud data comprises: generating, with at least one processor, a point cloud packet, the point cloud packet comprising a header portion and a data section, the data section comprising a plurality of blocks, each block comprising point cloud data; generating, with the at least one processor, a message sequence number (MSN); storing, with the at least one processor, the MSN in the data section; generating, with the at least one processor, a message authentication code (MAC) on the data section; storing the MAC in the point cloud packet; and transmitting, with the at least one processor, the point cloud packet to a receiving device.

Machines with credentials having multiple sensors can be authenticated and allowed a level of access to perform tasks based on the credential and a blockchain network or blockchain based platform using authenticatable values provided by the machines' sensor data, log data, location data. Requests for service can be managed by the blockchain based platform based on authentication values from the machine.

A mobility data storage method executed by a plurality of vehicles each including a sensor and a processor coupled to the sensor, the processor of each of the plurality of vehicles being configured to store a local blockchain, the method includes, with the processor of the plurality of vehicles, attaching a sensor data pool, a random value that excess a threshold, and a verifiable random function (VRF) proof to a respective candidate block then broadcasting the candidate block to all other vehicles. Then, a particular candidate block whose random value is largest among the broadcasted candidate blocks is selected and verified with the VRF proof prior to be attached to the local blockchain.
