1. A secure start system for an autonomous vehicle, the secure start system comprising:

  • a communications router;

    a compute stack storing a cryptographically signed and encrypted file system, and comprising a plurality of drives to execute the file system to enable an autonomous mode of the autonomous vehicle; and

    wherein the compute stack comprises a master node including one or more memory resources that execute secure start instructions, causing the secure start system to;

    based on detecting startup of the autonomous vehicle, transmit credentials to a backend authentication system via the communications router;

    receive, when the credentials are authenticated, a tunnel key from the backend authentication system;

    establish, using the tunnel key, a private communications session with a backend vault of the backend authentication system;

    retrieve a verification key and an autonomous key from the backend vault;

    verify, using the verification key, that the file system was cryptographically signed by the backend authentication system; and

    decrypt the file system using the autonomous key to enable the autonomous mode.
