Reducing the computational load on processors by selectively discarding data in vehicular networks

Abstract

A method is provided for efficiently processing messages staged for authentication in a security layer of a protocol stack in a wireless vehicle-to-vehicle communication system. The vehicle-to-vehicle communication system includes a host vehicle receiver for receiving messages transmitted by one or more remote vehicles. The host receiver is configured to authenticate received messages in a security layer of a protocol stack. A wireless message broadcast by a remote vehicle is received. The wireless message contains characteristic data of the remote vehicle. The characteristic data is analyzed for determining whether the wireless message is in compliance with a predetermined parameter of the host vehicle. The wireless message is discarded prior to a transfer of the wireless message to the security layer in response to a determination that the wireless message is not in compliance with the predetermined parameter of the host vehicle. Otherwise, the wireless message is transferred to the security layer.

Description

technical field [0001] Embodiments generally relate to vehicle-to-vehicle communication. Background technique [0002] Vehicle-to-vehicle (V2V) applications involve cooperative communication of vehicles based on two-way communication for real-time interaction. These systems are preferably used for traffic management, collision warning and collision avoidance. Such a system can extend the host vehicle's range of awareness of surrounding environmental conditions by providing relevant information about traffic conditions, in addition to any safety-relevant events occurring near the host vehicle or detected by vehicles near the host vehicle. [0003] Incorporating security protections on V2V applications entails substantial costs. The costs incurred are in the computational power required to handle the security issues, specifically (1) creating the security message at the transmitter; and (2) verifying the integrity of this security message at the receiving node.
