Abstract
A vehicle system includes a manager module, a node, and a wired vehicle communications network connecting the node and the manager module. The manager module is programmed to receive a request to publish or subscribe to a message topic from the node; authenticate the node using the request; authorize the node by verifying that the node is on a permission list for the message topic; and upon authenticating and authorizing the node, transmit a symmetric key to the node. The node is programmed to encrypt or decrypt messages about the message topic using the symmetric key.
