Security and Access Control for Vehicular Communications

In this paper, we present an architecture for security and access control in Intelligent Transportation Systems. The applicability of the proposed architecture is demonstrated by developing a case-study based on CVIS(collaborative vehicle infrastructure system). The proposed framework ensures maximum security for the communication infrastructure by implementing access control at both the data link layer and the network layer. The originality of the proposed framework consists on adoption of a universal security mechanism approach by using the Kerberos protocol for link layer authentication as well as for establishing IPSec security associations, which simplifies credential management and ensures reduced overhead. The operations of the EAP-Kerberos authentication method that we have designed and implemented for the purpose of this project is also presented.
