Abstract
A method in one embodiment includes intercepting a message in an on-board unit (OBU) of a vehicular network environment between a source and a receiver in the vehicular network environment, verifying the message is sent from the source, verifying the message is not altered, evaluating a set of source flow control policies associated with the source, and blocking the message if the set of source flow control policies indicate the message is not permitted. In specific embodiments, the message is not permitted if a level of access assigned to the source in the set of source flow control policies does not match a level of access tagged on the message. In further embodiments, the method includes evaluating a set of receiver flow control policies associated with the receiver, and blocking the message if the set of receiver flow control policies indicates the message is not permitted.

93. A system, comprising an electronic device in a vehicular network environment of a vehicle, the electronic device including at least one processor for:
-
detecting a trigger on an electronic device in a vehicular network environment of a vehicle; identifying an interface usage policy for an agent and a corresponding application on the electronic device; selecting a first wireless interface of a plurality of wireless interfaces on the electronic device for a network session between an application process of the application and a remote node, wherein the first wireless interface is selected based, at least in part, on one or more criteria in the interface usage policy; associating the electronic device with a controller in a network environment; associating the first wireless interface of the electronic device with a first wireless infrastructure device in the network environment; providing Internet Protocol (IP) mapping information to the controller; establishing a network session between the electronic device and the remote node through the first wireless interface, wherein packets of the network session are routed through the controller; intercepting a first message in the electronic device being sent from a first source to a first receiver; evaluating one or more predefined policies to determine whether the first source is permitted to communicate with the first receiver; blocking the first message if the first source is not permitted to communicate with the first receiver, wherein a first subsystem of the vehicular network environment includes one of the first source and the first receiver; intercepting a second message in the electronic device being sent from a second source to a second receiver in the vehicular network environment; verifying the second message is sent from the second source; verifying the second message is not altered; evaluating a set of source flow control policies associated with the second source; and blocking the second message if the set of source flow control policies indicates the second message is not permitted.
