Abstract
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.
