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.

Session key generation for autonomous vehicle operation

Among other things, techniques are described for provisioning and authentication of devices in vehicles. In one aspect, a device in a vehicle establishes a communication session with a network server that manages provisioning of devices corresponding to an enterprise associated with the vehicle. The device receives instructions from the network server to generate cryptographic keys, and in response, generates a public and private key pair. The device sends, to the network server, a certificate signing request that includes the public key and an identifier of the device. In response, the device receives a digital security certificate for the device, and a security certificate of a signing certificate authority. The device authenticates the security certificate of the certificate authority using a known enterprise root certificate, and upon successful authentication, stores the device security certificate and the security certificate of the signing certificate authority.

Device provisioning and authentication

This disclosure describes a cyber-security protocol for validating messages being exchanged between two devices of an autonomous vehicle. The protocol includes the independent generation of multiple encryption or session keys by both devices. The encryption keys are generated based on a random number provided by each device. In some embodiments, the random numbers can be accompanied by a shared secret key installed on both devices that can help prevent an unauthorized device from creating a shared set of encryption keys with one of the devices. Including a hash generated using one of the encryption keys and a message sequence counter value in each message can help prevent the injection of previously transmitted messages as a means of disturbing operation of the autonomous vehicle.

Cyber-security protocol

Among other things, techniques are described for managing power of electronic devices of a vehicle. For example, a vehicle includes a power source, a power distribution unit configured to control power to at least one electronic device from the power source, a first processor configured for communicating power commands to the power distribution unit, wherein the power distribution unit includes a second processor configured to execute the computer executable instructions stored in computer-readable medium for carrying out operations including adjusting a power distribution from the vehicle power source to the electronic device in accordance with policy data.

Controlling power of electronic devices on a vehicle

Among other things, we describe systems and method for implementing data security in an autonomous vehicle system. The systems and methods can include inter-process communication security via key management, in which asymmetric cryptography and other validation techniques are used to validate data received from sensors. The systems and method can also include penetrative testing, in which valid sensor inputs are modified and transmitted throughout a distributed network through one or more sensors.
