Managing Public Key Infrastructure for Securing Vehicular Ad Hoc Networks With Dr. Albert Wasef Department of Electrical & Computer Engineering University of Waterloo, Canada Faculty Host: David Castanon Refreshments will be served outside Room 339 at 1:45 p.m. Abstract: In last few years, vehicular ad-hoc network (VANET) emerged as an excellent candidate to change the lifestyle of the traveling passengers along the roads and highways in terms of improving the safety levels and providing a wide range of comfort applications. Due to the foreseen impact of VANETs on our lives, extensive attention in industry and academia are directed toward bringing VANETs into real life and standardizing their network operation. Unfortunately, the open medium nature of wireless communications and the high-speed mobility of a large number of vehicles in VANETs pose many challenges that should be solved before deploying VANETs. It is evident that any malicious behaviour of a user, such as injecting false information, modifying or replaying the disseminated messages, could be fatal to other legal users. Public Key Infrastructure (PKI) is a well-recognized solution to secure VANETs. However, the traditional management of PKI cannot meet the security requirements of VANETs. In addition, some security services such as fast authentication cannot be provided by the traditional PKI. Consequently, to satisfy the security and privacy requirements, it is a prerequisite to elaborately design an efficient management of PKI to achieve the security requirements for practical VANETs. In this presentation, we present the current IEEE standard for VANETs and the basic operation of VANETs. Moreover, we propose an efficient Distributed Certificate Service (DCS) scheme for vehicular networks. The proposed scheme offers a flexible interoperability for certificate service in heterogeneous administrative authorities and an efficient way for any On-Board Units (OBUs) to update its certificate from the available infrastructure Road-Side Units (RSUs) in a timely manner. In addition, the DCS scheme introduces an aggregate batch verification technique for authenticating certificate-based signatures, which significantly decreases the verification overhead.
