METHOD FOR CONTROLLING ACCESS TO AN IN-VEHICLE WIRELESS NETWORK

摘要

Disclosed is a technique for managing access by a portable device to an in-vehicle router system (IVRS). The IVRS determines network access privilege of the portable device located within the vehicle. The portable device determines whether it is connected to a wireless access point (AP) of the IVRS or a rogue network. The portable device transmits a first token to the wireless AP, via a first communication link implementing a first protocol stack, to prompt the wireless AP to reply with a second token. The portable device receives the second token via a second communication link implementing a second protocol stack different than the first protocol stack between the portable device and the IVRS. The portable device determines whether the second token matches the first token. If the second token is determined to match the first token, the portable device authenticates the wireless AP.

1. A method comprising:
transmitting, by a portable device located within a vehicle, a first token to a wireless access point (AP) associated with an in-vehicle router system (IVRS) of the vehicle, via a first communication link, to prompt the wireless access point to reply with a second token, the first communication link implementing a first protocol stack; receiving, by the portable device, the second token via a second communication link between the portable device and the IVRS, the second communication link implementing a second protocol stack different from the first protocol stack; determining, by the portable device, whether the second token matches the first token; and authenticating the wireless AP, by the portable device, only when the second token has been determined to match the first token.
