System and method for wireless interface selection and for communication and access control of subsystems, devices, and data in a vehicular environment

A method comprising:

• 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.

An on-board unit (OBU) of a vehicular network environment, the OBU comprising:

• at least one processor;
• and
• an information flow control monitoring module adapted, when executed by the at least one processor, to:
• intercept a message in the OBU between a source and a receiver in the vehicular network environment;
• verify the message is sent from the source;
• verify the message is not altered;
• evaluate a plurality of flow control policies associated with the source and the receiver;
• and
• block the message if one or more of the plurality of flow control policies indicate the message is not permitted.

At least one non-transitory computer readable storage medium having instructions stored thereon that, when executed by at least one processor, cause the at least one processor to:

• intercept a message in an on-board unit (OBU) of a vehicular network environment between a source and a receiver in the vehicular network environment;
• verify the message is sent from the source;
• verify the message is not altered;
• evaluate a set of source flow control policies associated with the source;
• and
• block the message if the set of source flow control policies indicate the message is not permitted.

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.
