Secure Position-Based Routing for VANETs

Vehicular communication (VC) systems have the potential to improve road safety and driving comfort. Nevertheless, securing the operation is a prerequisite for deployment. So far, the security of VC applications has mostly drawn the attention of research efforts, while comprehensive solutions to protect the network operation have not been developed. In this paper, we address this problem: we provide a scheme that secures geographic position-based routing, which has been widely accepted as the appropriate one for VC. Moreover, we focus on the scheme currently chosen and evaluated in the Car2Car Communication Consortium (C2C-CC). We integrate security mechanisms to protect the position-based routing functionality and services (beaconing, multi-hop forwarding, and geo-location discovery), and enhance the network robustness. We propose defense mechanisms, relying both on cryptographic primitives, and plausibility checks mitigating false position injection. Our implementation and initial measurements show that the security overhead is low and the proposed scheme deployable

Security architecture for vehicular communication

Abstract — Despite recent progress for vehicular communication in research, development, field tests, and standardization, security is still in an early phase though it represents a crucial part of the vehicular communication system. So far, no vehicular security architecture has been proposed which integrates existing individual solutions for vehicle registration, data integrity, authentication, and so on. By description of different architectural perspectives, we identify the stakeholders and their responsibilities. Then, we focus on the functional layer view and highlight the concepts which jointly secure the vehicular communication. Based on these concepts, we present an implementation approach which introduces the security concepts into the protocol stack of a vehicular communication system. The proposed security architecture follows a clean and modular design. It is the basis for our prototype implementation which will serve as a proof-of-concept. We will also submit this architecture to the ongoing standardization process of the Car2Car Communication Consortium (C2C-CC). I
