1. A method for authenticating a data transmission originating from a source and received at a vehicle, the method comprising:
receiving, at the vehicle, the data transmission from a transmitting device positioned offboard of the vehicle, the data transmission (i) being a voice communication and (ii) including payload data and control data, the control data including a cryptographic identification of the source;
wherein the cryptographic identification of the source of the control data is embedded as a human inaudible component of the voice communication with the payload data into the data transmission; and
wherein an audio processing device is configured to detect the human inaudible component;
decrypting the cryptographic identification of the source, thereby identifying the source;
determining whether the source is authorized based on the decrypted cryptographic identification; and
generating a control action based on whether the identified source is authorized.
