Cryptographically secure mechanism for remotely controlling an autonomous vehicle

A non-transitory computer readable storage medium for tangibly storing computer program instructions capable of being executed by a computer processor, the computer program instructions defining steps of:

• receiving, by a second autonomous vehicle, a message from a first autonomous vehicle, the message including a signed body portion and a triple, the signed body portion comprising an order to remotely control the second autonomous vehicle and the triple comprising a public identifier of the first autonomous vehicle, a public key of the first autonomous vehicle, and a certificate of the first autonomous vehicle, wherein the public identifier is generated at least in part on a unique device secret of the first autonomous vehicle and wherein the certificate comprises an encrypted ciphertext generated by encrypting the public key;
• authenticating the message by verifying the certificate of the first autonomous vehicle;
• logging the message into a blockchain storage structure, the blockchain storage structure storing a plurality of blocks, each blocking including the signed body portion;
• executing one or more orders included within the signed body portion;
• and
• transmitting a second message to the first autonomous vehicle, the second message including a second signed body portion that includes a response to the order to remotely control the second autonomous vehicle.

A device comprising:

• a processor;
• and
• a storage medium for tangibly storing thereon program logic for execution by the processor, the stored program logic comprising logic performing steps of:
• receiving, by a second autonomous vehicle, a message from a first autonomous vehicle, the message including a signed body portion and a triple, the signed body portion comprising an order to remotely control the second autonomous vehicle and the triple comprising a public identifier of the first autonomous vehicle, a public key of the first autonomous vehicle, and a certificate of the first autonomous vehicle, wherein the public identifier is generated at least in part on a unique device secret of the first autonomous vehicle and wherein the certificate comprises an encrypted ciphertext generated by encrypting the public key;
• authenticating the message by verifying the certificate of the first autonomous vehicle;
• logging the message into a blockchain storage structure, the blockchain storage structure storing a plurality of blocks, each blocking including the signed body portion;
• executing one or more orders included within the signed body portion;
• and
• transmitting a second message to the first autonomous vehicle, the second message including a second signed body portion that includes a response to the order to remotely control the second autonomous vehicle.
