Privacy, security, and reliability are key requirements in deploying vehicular ad-hoc networks (VANET). Without those the VANET technology won’t be suitable for market diffusion. In this chapter, the authors are concerned with how to fulfill these requirements by using pseudonym-based authentication, designing security schemes that don’t endanger transport safety while maintaining low overhead. At the same time our design improves the system usability by allowing nodes to self-generate their own pseudonyms.
Chapter Preview


We present the idea of self-generation of pseudonyms in our previous work (Calandriello et al., 2007). Zeng (2006) presents the same approach independent of our work, and Armknecht et al. (2007) apply it to VANET. Calandriello et al. (2007) show that the proposed optimizations can also be applied to the cryptosystem presented by Zeng (2006).
