Abstract
An example apparatus comprises a processing resource coupled to a memory resource. The processing resource may be configured to execute instructions stored on the memory resource to generate a first secure key including a private key stored by a vehicle, generate a first secure message including the first secure key, transmit the first secure message over a vehicle bus to a vehicle part associated with the vehicle, and receive, from the vehicle part, a second secure message including at least one of a vehicle identification number (VIN) and a configuration parameter corresponding to the vehicle part in response to a determination that the first secure key matches a secure key corresponding to the vehicle part.
Claims11
An apparatus, comprising:
- a processing resource coupled to a memory resource, the processing resource to execute instructions stored on the memory resource to:
- generate a first secure key including a private key stored by an autonomous vehicle, wherein:
- the autonomous vehicle is to use secure data to perform one or more machine learning operations;
- and
- the private key is assigned to a replacement vehicle part to prevent unauthorized modification of the autonomous vehicle;
- update an anti-replay mechanism comprising at least one of a monotonic counter, a nonce value, a timestamp, or combinations thereof on power up of the vehicle;
- generate a first secure message including the first secure key;
- append a value associated with the anti-replay mechanism to the first secure message;
- transmit the first secure message over a vehicle bus to the replacement vehicle part associated with the autonomous vehicle and a control unit that includes a neural network to use the first secure message for the one or more machine learning operations;
- and
- receive, from the replacement vehicle part, a second secure message including at least one of a vehicle identification number (VIN) and a configuration parameter corresponding to the replacement vehicle part in response to a determination that the first secure key matches a secure key corresponding to the replacement vehicle part in order to facilitate a continual secure communication capability between the replacement vehicle part and the autonomous vehicle.

A method, comprising:
- generating a secure message comprising a vehicle identification number (VIN) associated with an autonomous vehicle and a private key associated with the autonomous vehicle, wherein the autonomous vehicle is configured to use the secure message to perform one or more machine learning operations;
- generating an anti-replay mechanism comprising at least one of a monotonic counter, a nonce value, a timestamp, or combinations thereof on power up of the vehicle;
- updating the anti-replay mechanism;
- appending a value associated with the anti-replay mechanism to the secure message;
- assigning the private key to a replacement vehicle part installed in the autonomous vehicle to prevent unauthorized modification of the autonomous vehicle;
- transmitting the secure message to at least one of a host computing device and the replacement vehicle part associated with a control unit that includes a neural network to use the secure message for the machine learning;
- decrypting the secure message using a key generated by at least one of the host computing device and the replacement vehicle part in order to facilitate a continual secure communication capability between the replacement vehicle part and the autonomous vehicle;
- and
- taking an action responsive to decrypting the secure message.
