Providing autonomous vehicle maintenance

A method comprising:

• generating a freshness indicator, the freshness indicator comprising an incrementing message counter;
• generating a session key based on a vehicle-specific key and the freshness indicator;
• generating a payload, the payload including the freshness indicator;
• generating a signature by executing a message authentication code (MAC) algorithm using the session key and the payload
• generating a packet comprising the payload and the signature, the signature generated;
• and
• transmitting the packet to the service provider.

A system comprising:

• a processor;
• and
• a storage medium for tangibly storing thereon program logic for execution by the processor, the stored program logic comprising
• logic, executed by the processor, for detecting a service condition in response to a fault occurring at an autonomous vehicle at a first location;
• logic, executed by the processor, for coordinating service with a nearby service provider, the service provider providing a time window and a second location;
• logic, executed by the processor, for predicting that the autonomous vehicle will be free to fulfill the service;
• logic, executed by the processor, for driving the autonomous vehicle to the second location of the service provider during the time window;
• and
• logic, executed by the processor, for returning the autonomous vehicle to the first location after the service is completed.
