Abstract:
Intelligent networking of cars and infrastructure (Car-to-X,
C2X) by means of dedicated short range communication represents one
of the most promising attempts towards enhancement of active safety
and traffic efficiency in the near future. Nevertheless, as an open
and decentralized system, Car-to-X is exposed to various attacks
against security and driver's privacy. This paper presents an
approach for enhancing security and privacy on physical layer,
i.e., already during sending and receiving of messages. This
technique is called Secure Beamforming. In previous works we
deployed a simulation-based approach for defining an antenna-array
appropriate for most of the safety-related use cases as defined by
the Car-to-Car Communication Consortium (C2C-CC).
In this paper we demonstrate a concept for integrating Secure
Beamforming into an overall Car-to-X system architecture. The
simTD architecture is thereby taken as the
reference architecture because of its detailed specification and
near-series alignment. We specify the components and interfaces
necessary to enable Secure Beamforming and furthermore define
beamforming protocols which are controlling the radiation pattern
of the simTD antennas for a secure sending
and receiving of messages.
